Amino acids are the monomers that make up proteins. Amino acids are made of a carboxyl group (Carbon, Oxygen, Hydrogen), an amino group (Nitrogen and two Hydrogen), and finally an R group which differs in each amino acid. That R group is what makes each amino acid different! They can also act as enzymes. Essentially enzymes act as biological catalysts and control the functions of the cell and build cells.
I believe CODIS still exist because if there is anything new about DNA in a laboratory, it will go straight to CODIS>
