Hydrogen bonds between the base portions of the nucleotides hold the two chains together. Genes are the basic units of heredity, composed of DNA sequences that contain instructions for building proteins and determining traits. Genes determine traits, such as eye color, height, and hair color. Genes are passed from parents to offspring and contain the information needed to specify physical and biological traits.

What is Genetics? Genetics is The science study that Focuses with the study of Heredity and Variation.

Heredity is about how traits are passed down from parent to offspring. Like spike, your entire DNA codes is in most of your body cells. DNA means Deoxyribonucleic Acid, DNA is made up of nucleotide. Nucleotide have 3 parts (1) Sugar- Deoxyribose, (2) Phosphate and lastly, (3) Base- the most important.

So far, There are 4 types of DNA, the A,T,C & G. Adenine, Thymine, Cytosine, & Guanine. DNA is also twisted something we call a "Double Helix" shape. Human has 46 Chromosomes. Human sperm and Egg Cells each contains 23 chromosomes. 23 from your dad and 23 from you mother.

In Conclusion, DNA means Deoxyribonucleic Acid. DNA is also a type of Nucleic Acid. Nucleic Acids are made up of Nucleotides.

Heredity is about how traits are passed down from parent to offspring, through asexual or sexual reproduction. Traits is a specific characteristics of a living organism, it's in our dna. Some of the traits we inherited from our parents can be influenced or changed by the environment.

For an example, if a person didn't have the nourishment they needed, it could affect their size or their growth. DNA determines how tall a person is, what their eye color is, what their hair color is, and even their risk for certain diseases. Your entire DNA code

is in most of your body cells. Just a simple hair follicle, nails, saliva can identify a person. DNA stands for Deoxyribonucleic Acid. It's a type of Nucleic acid. Nucleic acids are made of Nucleotides.

Nucleotides have 3 parts: Deoxyribose which is a sugar, Phosphate, and the Nitrogenous base which is the most important part because the sequence of the base can actually code for traits. There are 4 types of bases in our DNA: the Adenine, Thymine, Cytosine, and Guanine.

Adenine and Thymine are paired together and the same goes for Cytosine and Guanine. They are held together by Hydrogen bonds. Our DNA is also twisted in something we call a double helix shape.

Portions of DNA makes up genes, let's say a specific part of our DNA makes up a gene and genes can code for proteins.

Proteins is involved in producing the eye color pigment, proteins are involved in transport, in structure, in acting as enzymes, and protecting the body. But not all of gene are used to make protein, there are parts of DNA that are non coding, even though nearly all of our body cells have our entire DNA code, our body cells may only use certain portions of those genes. Genes can be turned on or off by a variety if mechanisms and we call this "Gene Regulation" Gene regulation refers to the processes that control when, where, and how much a gene is expressed, ensuring cells produce the necessary proteins and maintain proper function. All of us have lots of DNA, when it's compacted, it can be organized into a unit called chromosomes.

Humans have 46 chromosomes, sperm and egg cells each contain 23 chromosomes, so we receive 23

chromosomes from our mother and 23 chromosomes from our father which is the reason why we have 46 chromosomes, our genetic code. Like what i said earlier, humans inherit their traits, dna, etc.. from their mother and father, but in asexual reproduction, one only inherit from one parent.

Thats all, thank you.

Traits can be influenced by the environment, the environment changes a gene either it's DNA sequence or activity level. DNA or Deoxyribonucleic Acid will help you understand how inheritance works and also twisted in something we call a double-helix shape. Nucleic Acids are made up of building blocks called nucleotides and nucleotides have 3 parts: Deoxyribose (sugar), Phosphate, Nitrogenous base. The nucleotide is a base because the sequence of the bases actually code for traits. There are four types of bases in DNA: A (Adenine), T (Thymine), C (Cytosine), and G (Guanine).

DNA is essential for cells and traits because it contains the genes and needed for an organism to develop, survive and reproduce. Without DNA, cells cannot function without it.

DNA make up genes, genes are basic units of heredity that contain building proteins and determining traits. When DNA compacted, it can be organized into a unit called chromosome. Human have 46 chromosome, 23 from the sperm cell and 23 egg cell, so that's why we have 46 chromosome in total. Chromosome is a thread like structure composed of DNA and made of protein that serve to carry the genomic information cell to cell.

In conclusion, DNA (Deoxyribonucleic Acid) is a molecule that contains the instructions for how living things grow, develop, and function. There are four types of nitrogen bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in a specific way: A with T, and C with G, forming a twisted shape called a double helix. 🧬

Heredity in general, is about how traits are passed from the parents to their offspring. One’s traits are found and coded in their DNA or Deoxyribonucleic Acid. There are factors that can affect one’s development of traits, example are their living environment conditions. DNA is inherited from one’s mother and father. An offspring’s DNA is the combination of their parent’s. Cells in your body cannot function without DNA, in other words, DNA is the nuclei for all the cells that are in your body. DNA determines some of your physical traits like your height, eye color and hair color. It also determines your risk for certain diseases, especially if you have inherited it from your parents. DNA is a type of nucleic acid, and those acids are made up of building blocks called nucleotides. In nucleotides, there is a part called the nitrogenous base, in which it has four types, often classified as A,T,C,G.  They stand for Adenine, Thymine, Cytosine and Guanine, respectively. These types of bases pair up for their sequence and they are held together by hydrogen bonds, in which they pair up as A and T and C and G. These bases are what makes up our DNA. The amount and sequence of the bases will vary among different species and among different individuals. One’s DNA sequence is more similar to their parents, rather than other individuals of their species. As the DNA’s structure is a double helix, parts of the DNA are also genes. Genes can code for proteins. For example, your genes can code for the amount of proteins that are used to produce eye pigment, and the same goes to your skin color, hair color, etc. Not all genes produce proteins, and not all parts of the DNA are coding. When DNA is compacted, it is organized into a unit called a chromosome. Humans have 46 chromosomes. A human sperm and an egg cell each contain 23 chromosomes, in which we received 23 chromosomes each from our parents, and that makes up of the 46 chromosomes that we have on our body. Chromosomes consist of genes that carry our DNA. And that DNA consists of bases and nucleotides, that makes the difference when coding traits. 

The DNA or deoxyribonucleic acid, is a nucleic acid that carries the genetic code determining traits in living organisms. It is made of building blocks called nucleotides, consisting of a 3 parts called deoxyribose, phosphate, and nitrogenous base. The base as the most important part because it codes for our traits. There are four bases in DNA: adenine, thymine, cytosine, and guanine. The DNA is structured as a double helix, that is held together by hydrogen bonds between base pairs. Meanwhile, portions of DNA make ups genes. Genes can code for proteins. Proteins play a huge role in DNA organization and gene expression. But, not all genes are used to make proteins. Genes can be turned on or off by different mechanisms in which we call this as gene regulation. When DNA is compacted it can be arranged into units called chromosomes. Us humans have 46 chromosomes. However, sperm and egg cells contain only 23 chromosomes each. We recieve 23 from our mother and another 23 from our father that is why we recieve a total of 46 chromosomes.

DNA stands for Deoxryibonucleic Acid it is a type of Nucleic Acid, and nucleic acids are a type of biomolecule. Nucleic Acids are made up of building blocks called Nucleotides. Nucleotides consist of 3 parts. Sugar, Phosphate, and the most important, the Nitrogenous Base. The sequence of the base can code for traits. There are four type of bases in DNA. Adenine, Thymine, Cytosine, and Guanine. These pair in a specific way. And these are the bases in living organisms.

The amount of the DNA sequences and bases can vary in different species and different individuals. The bases are held together by Hydrogen Bonds, the DNA also has a specific shape called a Double Helix. Portions of DNA make up genes, genes code up protein, and protein has a huge part in expressing traits.

Proteins are involved in transport, in structure, in acting as enzymes, in protecting the body and much more. But not all genes are used to make protein. Genes can be turned on or turned off by a variety of mechanisms, it is called Gene Regulation.

Chromosomes in your body involve DNA wrapped around protein structures. We humans have 46 chromosomes, meaning nearly every cell in our body have chromosomes. But egg cells and sperm cells each contain 23 chromosomes. 23 from your mother, and 23 from your father to give you a total of 46 chromosomes.

Understanding this foundation is essential for understanding heredity.

It is also mentioned in the video that there are 4 types of DNA. A (adenine), T (thymine), C (cytosine), and G (guanine). These are bases that pair in a specific way. All of the living things has the same DNA bases (T&A) and (C&G). The DNA is also twisted and it is called double-helix shape, some portions of DNA make up genes, genes can code for proteins, it can have a huge role in expressing traits, proteins is involved in transport, structure, in acting as enzymes, and in protecting the body and so much more. But not all genes are used to make protein. Our body cells may only use portions of those genes, because genes can be turned on or turned off it is called gene regulation.

Chromosome is also tackled in the video it means when DNA is compacted it can be organized into a unit and that is called chromosomes. It involves DNA wrapped around protein structure, human have 46 chromosomes that means every body cells in our body has 46 chromosomes. On the other hand human sperm and egg cells contain 23 chromosomes. Overall I learned how DNA is important for us, and how genes is passed down.

Heredity is the passing of traits from parents to offspring. It's all thanks to DNA, the blueprint of life!

DNA (Deoxyribonucleic Acid) is a long, complex molecule that contains the genetic instructions for building and maintaining an organism. It's like a recipe book for life, filled with instructions for everything from eye color to height.

Chromosomes are tightly packed bundles of DNA found in the nucleus of every cell. Humans have 23 pairs of chromosomes, one set from each parent.

Genes are specific segments of DNA that code for a particular trait. Each gene has a specific location on a chromosome. For example, there's a gene for eye color, a gene for hair color, and so on.

Traits are the characteristics that we inherit from our parents, like our eye color, hair color, height, and even some aspects of our personality. These traits are determined by the combination of genes we receive from our parents.

Here's a simple analogy:

- Imagine DNA as a cookbook.

- Chromosomes are the chapters in the cookbook.

- Genes are individual recipes within those chapters.

- Traits are the finished dishes that result from following those recipes.

Understanding these basic concepts helps us grasp the fundamentals of heredity and how we inherit traits from our parents!

two strands of nucleotides.

Nucleotides have three parts,

deoxyribose (a sugar), phosphate,

and the most important part, the

base. Bases codes for traits, and

there are four types: adenine,

thymine, cytosine, and guanine.

Guanine pairs with cytosine, while

adenine pairs with thymine. Portions

of DNA make up genes, and genes can code for proteins. Proteins play a major role in expressing traits, which is why most families share similar traits due to their genes. Not all genes are used to make proteins, though. Genes can be turned on or off by a variety of mechanisms, a process known as Gene Regulation. When a lot of DNA is compacted, it is organized into a unit called a

chromosome. Humans have a total of

46 chromosomes. Therefore, each of

your parents gave you 23 chromosomes. Understanding all of

this is essential for understanding

heredity. This is all the information and knowledge I have gained from watching the video.

DNA(Deoxyribo Nucleic Acid) - the molecule that carries genetic instructions for the development and functioning of organisms, acting as a blueprint for building and maintaining life.

CHROMOSOMES - it is found within the nucleus cells,that contain an organism's genetic information.The human body composed of about 46 chromosomes

GENES - basic unit of heredity, genes are pass through other generations cause of DNA, if your father have a talent like moving an ear without touching, it's possible that you may also have that talent cause of Genes.

TraitsTraits - a specific characteristic of an organism, that can be influenced by genes and the environment.Some Traits a DOMINANT, which means they are the most powerful then sa RECESSIVE.

If you are like your Father, Physically and Mentally, means that the trait of your father is dominant, and your mother's trait is recessive.

HEREDITY - passing a trait from the mother/father on to their offspring (children), because the offspring's cells or organism acquire the parent's genetic information.

Heredity is also known as inheritance or biological inheritance.

For me, the passing a trait through the parent to their offspring is obviously true, because my Father, in his teenage time, suffers alot from manarism, and know he can handle it, meanwhile, I also have a manarism.

NUCLEIC ACID/S - is/are made up of building blocks that are called NUCLEOTIDES which has a 3 Type

Types of Nucleotides:

deoxyribose

phosphate

Base

The most important part of Nucleotides is the Base, because bases coded for the traits

Base has a 4 type

Types of Base:

Adenine

Thynine
