Question

The number of amino acids in a polypeptide chain is 150. The number of mRNA bases required is: given species:
(A) 150
(B) 450
(C) 100
(D) 50

Answer 1

Hint:
A polypeptide is a non-branched, continuous chain of amino acids that is bonded together by peptide bonds. By joining the carboxyl group of one amino acid to the amine group of the following amino acid, the peptide bond creates an amide.

Complete step by step answer:
Proteins are made up of substances called amino acids. Proteins and amino acids are the components of life. Amino acids are the end products of the digestion or breakdown of proteins or polypeptides. Amino acids are used by the human body to create proteins. A basic amino group (NH2), an acidic carboxyl group (COOH), and an organic R group (or side chain) that is specific to each amino acid make up an amino acid, an organic molecule.
Body protein as well as other vital nitrogen-containing substances including creatine, peptide hormones, and some neurotransmitters cannot be produced without amino acids. Although allowances are expressed in terms of protein, amino acids are a biological necessity. The substances known as amino acids, or the "building blocks of proteins," play a variety of vital functions in your body. You require them for essential functions like producing hormones, neurotransmitters, and proteins.
In meals high in protein for example meat, fish, and soybeans, amino acids are concentrated. An amino acid is coded by a triplet of nitrogen bases known as a codon.

Option ‘B’ is correct

Note:
The main structure of a polypeptide chain is the distinctive arrangement of amino acids. For instance, the polypeptide chains A and B of the pancreatic hormone insulin are joined by disulfide bonds.
