How are proteins affected by your DNA composition?

Answer 1

Affected? Hell, they're MADE from your DNA, pretty much... though of course they'e not made OF DNA - proteins consist of one or more polypeptide chains (which are chains of amino acids linked by peptide bonds).

But, in short - your DNA is transcribed into mRNA (by particular enzymes, and enzymes are also proteins by the way...) - so basically a copy is made of your DNA - which is then translated into a polypeptide in little cell organelles called ribosomes - each 3 bases of DNA (or mRNA if you like...) codes for a particular amino acid, which is sort of brought to the ribosome by a tRNA molecule....

You know the bases, right? A, T, C, G, U (Adenine, Thymine, Cytosine, Guanine, Uracil)? Well, Adenine always binds with thymine, and cytosine always binds with guanine... and Uracil is the RNA equivalent of thymine. so here's an example of how it works (assuming the top strand of DNA is transcibed):

Answer 2

well DNA is the code or instructions to make protein so it will greatly affect it and it will most likely seriously hurt the animal or human with mutated DNA

Added: Most likely the mutation will be neutral, but proteins can be misshapen if the code translates into another amino acid. Sometimes, such as in the sickle mutation, one amino acid change can be beneficial. Depends on the environment many times.

Answer 3

DNA provides the instructions for building proteins through a process called protein synthesis. The sequence of nucleotides in DNA determines the sequence of amino acids in a protein. Mutations in the DNA sequence can lead to changes in protein structure and function, affecting the cell's ability to carry out its normal processes.
