Explanation:
Detailed explanation-1: -Polypeptides containing more than 100 amino acids having molecular mass higher than 10, 000 are generally called as proteins.
Detailed explanation-2: -Although more than 100 amino acids occur in nature, particularly in plants, only 20 types are commonly found in most proteins. In protein molecules the -amino acids are linked to each other by peptide bonds between the amino group of one amino acid and the carboxyl group of its neighbour.
Detailed explanation-3: -In order for a protein with 100 amino acids to be produced, the messenger RNA must at least be 303 nucleotides in length.
