DNA

claramello271_1 — 2023-11-23 00:31:54 UTC

DNA is the molecule that carries all our genetic information. All living organisms have DNA since it is like an instruction manual for our bodies, which allows us to have different traits.

mRNA

claramello271_1 — 2023-11-23 00:39:35 UTC

mRNA (messenger RNA) is a molecule that carries information from the DNA which is inside the nucleus, to where the protein is being created, which is located outside of the nucleus in the cytoplasm (ribosomes).

tRNA

claramello271_1 — 2023-11-23 00:45:13 UTC

t RNA (transfer RNA), is a small molecule that has a significant role in the process of the creation of protein. In this process, it serves as a connector between the mRNA and the chain of amino acids being formed. t RNA also has the role of adding its matched sequence onto the mRNA molecule each time a new amino acid is added to the growing chain.

Transcription

claramello271_1 — 2023-11-23 00:47:31 UTC

The process in which DNA is transformed into mRNA (messenger RNA) through transcription. The transcription process begins when the mRNA splits the the Spiraled DNA and then the tRNA goes through it creating a brand new code with the bases A, C, G, and U. With this, an amino acid chain is created, it leaves the nucleus and goes to the cytoplasm as the chain crumbles up together and creates the protein. This allows the instruction to be carried to a different part of the cell.

Translation

claramello271_1 — 2023-11-23 00:47:42 UTC

Translation takes place in the cells cytoplasm where the mRNA is read by the ribosome which reads each codon 3 by 3, then the tRNA attaches itself creating the chain of amino acids which them creates the protein.

Bases

claramello271_1 — 2023-11-23 00:48:07 UTC

Bases are molecules that make up the nucleotides. Bases are arranged in pairs when we look at the DNA structure and each base has a set pair that cannot be changed for another. Each base is defined by its letter, in total we have: A, T, C, G. A always goes with T, T always goes with A, C always goes with G, G always goes with C. For the RNA, there is no T, so A would always go with U during the process in which the protein is made.

Deletion

claramello271_1 — 2023-11-26 15:16:32 UTC

Deletion is a type of mutation where one or more nucleotide is deleted from the DNA sequence, which is one of the more harmful types of mutations. The only way to minimize the impact of a deletion is to have an addition mutation in the same sequence, which will return the balance of quantity between the nucleotides.

Substituition

claramello271_1 — 2023-11-26 15:16:41 UTC

Substitution is a type of mutation where a nucleotide in the DNA sequence is substituted for another. For example if in the original sequence it was G, then after substitution it became A or any other base other than G. In substitution, the amino acid produced can either be the same or different, depending on what was changed in the DNA sequence.

Silent Mutation

claramello271_1 — 2023-11-26 15:16:51 UTC

A silent mutation is when a mutation occurs in the DNA sequence but the nucleotide changed has no visible affect on the amino acid created, therefore the protein will be the same, as if there were no mutations.

Insertion

claramello271_1 — 2023-11-26 15:17:10 UTC

Insertion is a type of mutation where one or more nucleotide is added somewhere in the DNA sequence. The affect of an insertion mutation can be none at all, or cause a new amino acid to appear in the chain, which can disrupt the protein being created and in some cases its function as well.

Mutation

claramello271_1 — 2023-11-26 15:17:17 UTC

Mutation is when a genes structure changes slightly, which will then be passed on to the next generations, such as being born with red hair. Mutation is also the alteration, rearrangement, addition, or deletion of a single base unit in DNA. There are various types of mutations, for example insertion and deletion. An insertion mutation is when there is an addition of one or more nucleotides into the segment of the DNA. Deletion is the opposite of insertion, meaning that one or more nucleotides are deleted from the sequence.

Reccesive

claramello271_1 — 2023-12-11 00:19:17 UTC

A recessive gene is one that can be covered if one of the two parents has a dominant gene, this means that in order to have a trait that is carried by a recessive trait, both parents would need to have that gene.

Melanin

claramello271_1 — 2023-12-11 20:57:07 UTC

Melanin is the amount of pigment in an individuals skin, eyes, and hair. The darker these features are the darker they will be. For example if we were to consider someones skin color, the darker it is the more melanin this person has. Someones amount of melanin can be caused by many different factors, such as heredity, geographical location, sun exposure, and other everyday habits such as diet.

Codominance relates to a type of heredity where the two alleles are expressed differently, in other words they are expressed in Heterozygote.

Connection: Dominant, Codominant, Recessive

claramello271_1 — 2023-12-11 21:53:25 UTC

All three of these terms refer to how powerful a certain trait is depending on which parent has it, this means that if we were to put certain situations into punnet squares to calculate the different possibilities for offspring, some would always take over other traits. For example we know that dominant, is a more powerful gene than a recessive one, but that still does not exclude it from possibility.

Connection: genotype and Phenotype

claramello271_1 — 2023-12-12 01:55:49 UTC

As Genotype refers to specific DNA sequence that is unique in each individual and codes for different traits, the phenotype is what translates those sequences into a physical trait in someones appearance

claramello271_1 — 2023-12-12 02:00:19 UTC

A Dominant allele is the one most likely to be an offsprings final trait if one or both parents posses it, therefore it will be their Phenotype.

Connection: Phenotype and inheritance

claramello271_1 — 2023-12-12 02:03:58 UTC

genes someone inherits from both their parents can either be dominant, codominant, or recessive, each can help predict the phenotype of offspring, which means the traits that they inherit from each parent.

Connection: Inheritance and Skin color

claramello271_1 — 2023-12-12 02:08:50 UTC

every single aspect of us that includes features is inherited from our parents, which means that skin color is one of them. Even though our skins pigment can be modified by sunlight exposure, parents skin color does have a sever impact on the offsprings skin tone as well.

Connection: Skin color and Melanin

claramello271_1 — 2023-12-12 02:13:07 UTC

Our skin color, is determined by the pigmentation present in it, which we already know is inherited from both parents. However the skin pigment is made up of different quantities of melanin. for example the darker the skin, the more melanin is present in it, and the lighter the skin, the less melanin present.

Connection: Skin color and Diversity

claramello271_1 — 2023-12-12 02:17:02 UTC

Skin color is one of the many aspects that make each human being unique and one society has the most difficulty accepting that no matter someones skin color, as we are all equal. Skin color can often be linked to race and where someone originates from geographically, which is also an aspect of diversity.

Connection: melanin and UV rays

claramello271_1 — 2023-12-12 02:21:21 UTC

Even if the amount of melanin in someone skin is initially impacted by heredity, further along in an individuals life other aspects can cause the amount of melanin to change in their skin depending on habits and exposure to the sun, which reflects UV rays. UV rays can be extremely harmful to our skin cells, which is why the amount of melanin increses when in contact with large amounts of it to serve the perpose of protection. This is because the darker a skin is pigmented, the more protected it is from UV rays.
