How do you go from gene to protein?
... Each chromosome is made of many genes. Each gene is made up of a specific DNA sequence which codes for a specific amino acid sequence, otherwise called a protein. These proteins result in the presence or absence of particular traits, or phenotypes. The process of going from gene, or DNA, to protein ...
