DNA. What is it made of? How does it makes us what we are? How and why do we share the same DNA with animals, plants, fruits, etc. ?
In: Biology
DNA or Deoxyribonucleic Acid, is an extremely complex molecule made up of 4 proteins (often called nucleotides), Adenine, Thymine, Guanine, and Cytosine. When sequencing DNA we write it as a sequence of the first letter of these, for example:
AATGCTTCAGT
DNA is stored in the nucleus of a cell and is used to encode for proteins our cells and the cells of other organisms need to function. It is sent as mRNA (Messenger RNA) which is basically one half of a chain of DNA to a ribosome which creates the proteins.
Depending on what proteins your specific DNA codes for, you may look different, these can effect skin tone, eye color, hair color, how much hair you have etc.
We share a lot of DNA with animals and plants because those encode for the proteins every living organism needs, like ATP, the protein cells burn for energy
