The passing of traits from parents to offspring is known as heredity, therefore, genetics is the study of heredity. ]]> 2020-06-01 03:14:34 UTC https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/603991611 DNA isabellaparenti2022 https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/603994742 Genetics its built around molecules called DNA.
Deoxyribonucleic acid or DNA, contains our genetic code, the blueprint of life. This essential molecule is the foundation for the “central dogma of biology”, or the sequence of events necessary for life to function. DNA is a long, double-stranded molecule made up of bases, located in the cell’s nucleus.]]> 2020-06-01 03:19:22 UTC https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/603994742 RNA isabellaparenti2022 https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/603999413 To ‘read’ these blueprints, the double-helical DNA is unzipped to expose the individual strands and an enzyme translates them into a mobile, intermediate message, called ribonucleic acid or RNA. This intermediate message is called messenger RNA (mRNA), and it carries the instructions for making proteins. ]]> 2020-06-01 03:26:41 UTC https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/603999413 isabellaparenti2022 https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604008113 2020-06-01 03:39:51 UTC https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604008113 Genes isabellaparenti2022 https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604008631 A gene is a specific segment of a DNA molecule that holds the information for one specific protein. DNA molecules have a unique code for each gene which codes for their specific protein. Some organisms can have more than 100,000 different genes so they will have 100,000 unique sequences of DNA ‘code’.
Genes are the basic unit of heredity. The genes of an individual are determined by their parent or parents. ]]> 2020-06-01 03:40:42 UTC https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604008631 isabellaparenti2022 https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604011519 2020-06-01 03:44:46 UTC https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604011519 Chromosomes isabellaparenti2022 https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604012216 Chromosomes are tiny structures inside cells made from DNA and protein. The information inside chromosomes acts like a recipe that tells cells how to function and replicate. Every form of life has its own unique set of instructions.
The chromosomes describe what color eyes you have, how tall you are, and whether you're a boy or a girl.]]> 2020-06-01 03:45:59 UTC https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604012216 isabellaparenti2022 https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604017491 2020-06-01 03:53:25 UTC https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604017491 Gregor Mendel isabellaparenti2022 https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604019989 Gregor Mendel, was a monk that through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He created The Law of Segregation, The Law of Independent Assortment and The Law of Dominance.]]> 2020-06-01 03:57:00 UTC https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604019989 isabellaparenti2022 https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604022843 2020-06-01 04:01:23 UTC https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604022843 Mitosis isabellaparenti2022 https://padlet.com/isabellaparenti2022/636mxfxxp9n964z5/wish/604023204 Mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA. And one cell gives rise to two genetically identical daughter cells.

  1. In the Prophase, you need to duplicate DNA, get certain pieces in the right position, and generally prepare the cell for the process of mitotic division. 
  2. In the Metaphase, the DNA lines up along a central axis and the centrioles send out specialized tubules that connect to the DNA that has now condensed into chromosomes. 
  3. In the Anaphase, half of the chromosomes are pulled to one side of the cell and half go the other way.
  4. In the Telophase, its time when the cell membrane closes in  and splits the cell into two pieces.
  5. And the last phase; the Interphase, its the resting state. Its just going about its daily business of surviving and making sure it has all of the nutrients and energy it needs. It is also getting ready for another division that will happen one day.

Is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells ; sperm in males, eggs in females.

  1. Meiosis I: Pairs of chromosomes are lined up at the center of the cell and then pulled to each side. The crossing over which happens with the DNA, is an exchange of genes. The cell divides, leaving two new cells with a pair of chromosomes each.
  2. Meiosis II: In Prophase II, the DNA that remains in the cell begins to condense and form short chromosomes. The centrioles also begin their journey to opposite sides of the cell. In Metaphase II all of the chromosomes line up along the center of the cell and the centrioles are in position for the duplication. Anaphase II, shows the chromosomes split and move to opposite sides of the cell, they split the DNA that exists.  And Telophase II, shows the DNA completely pulled to the sides and the cell membrane begins to pinch. The gametes will find other gametes with which they can combine. After that, they will form a new organism.
