Principle Of Inheritance And Variation Question 339
Question: 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
Options:
A) 26
B) 36
C) 42
D) 39
Show Answer
Answer:
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.
