2023 Manipur Molecular Basis of InheritanceSalient features of the genetic code Medium Question 40 of 200 in Molecular Basis of Inheritance

The salient features of genetic code are: (A) The code is palindromic (B) UGA act as initiator codon (C) The code is unambiguous and specific (D) The code is nearly universal. Choose the most appropriate answer from the options given below:

A (A) and (D) only
B (B) and (C) only
C (A) and (B) only
D (C) and (D) only

The answer is D.

Solution

The genetic code is unambiguous and specific (each codon codes for only one amino acid) and is nearly universal (the same across most organisms) — C and D are correct salient features. The genetic code is not palindromic (A is incorrect), and UGA is actually a stop codon, not the initiator codon (AUG is the initiator; B is incorrect).
