Question

In protein synthesis the base sequence of mRNA determines the primary structure of polypeptide chain because

• A. it determine the sequence of alignment of amino acid charged $ tRNA $ molecule
• B. there is one to one coding relationship between each base on mRNA and amino acid
• C. each amino acid is defined by a pair of base on $ mRNA $
• D. amino acid molecule align directly on the polynucleotide on $ mRNA $

Answer 1

Answer: (A)

During the process of translation, the codons present on mRNA decides the sequence of amino acids (primary structure) on polypeptide chain. These amino acids later forms secondany structure by forming various bonds.
