How do you determine which amino acid is incorporated in the protein?

Answer 1

The amino acids are determined by the codons in the RNA sequence that the protein is being made from. The RNA originally came from copying a DNA sequence in the nucleus.
A codon is a group of 3 nucleotides. Check the link I provided below for a list of codon codes and the amino acids that they determine.

hmm, It won't let me submit my answer with the link
You'll just have to go to wikipedia and do a search for codons

Answer 2

Hi Savannah this ones for you
A short chain of amino acids is referred to as a peptide (or oligopeptide); a long chain of many (hundreds or thousands) amino acids is referred to as a polypeptide.
Each cell makes thousands of different KINDS of proteins.
Different kinds of proteins are composed of a different sequence of amino acids.
For example, the first six amino acids in actin (a protein involved in muscle contraction and the cytoskeleton) are: Methionine, then cysteine, then aspartic acid, then asparagine, then asparagine, then valine.
The first six amino acids in beta-globin (part of hemoglobin, the protein that transports oxygen in our blood) are: Methionine, then valine, then glutamine, then leucine, then serine, then serine.
Proteins typically consist of MANY amino acids. For example, actin consists of more than 300 amino acids. A complete hemoglobin molecule has around 600 amino acids. A single antibody molecule (part of the immune system) contains about 1,400 amino acids or more.
The SAME protein consists of the SAME sequence of amino acids. For example, if actin is a protein consisting of a chain of 376 amino acids, then EVERY actin protein will be 376 amino acids long, and EVERY actin protein will have the same amino acid sequence, starting with methionine, cysteine, aspartic acid, asparagine, asparagine, and
As a result, different amino acids have different chemical properties. Each kind of protein is a unique combination of different amino acids, and the properties of a protein are determined by the amino acids used to make it.
For example, proteins that are found in membranes contain many hydrophobic amino acids, because the interior of membranes is a hydrophobic environment.
