AIIMS 2019 Botany Genetic Code MCQ Question
Type: MCQ-fact-Easy-Class 12
Correct sequence for Alanine code:
A
GCU, GCC, GCA
Correct Answer
Option A
Detailed Explanation
Option A is correct because the codons GCU, GCC, and GCA are all part of the genetic code that specify the amino acid alanine (Ala). These codons are recognized by transfer RNA (tRNA) during translation, facilitating the incorporation of alanine into polypeptide chains. The other options are marked as N/A, indicating they do not provide relevant codons for alanine, thus lacking the necessary information to be considered correct. Understanding the genetic code is essential for grasping how sequences of nucleotides in mRNA translate into functional proteins.
