NEET Biology Principle Of Inheritance And Variation Question Bank Protein Synthesis

  • question_answer
    A polypeptide is produced as dictated by mRNA, the number of bases on the mRNA that code for the polypeptide portion containing N-terminal amino acid and next 13 amino acid is

    A) 26

    B) 36

    C) 42

    D) 39

    Correct Answer: C

    Solution :

    One amino acid is coded by triplet base (3 bases) so for 13 amino acids 13 × 3 = 39 bases are required and 3 bases are required for the formation of N terminal amino acid from methionine. Hence total 39 + 3 = 42 bases are required.
