The anticodon for GCG is:
A) AUA
B) CCT
C) UAU
D) CGC
**D
The correct anticodon for the codon GCG is D) CGC.
To determine the anticodon for GCG, you need to understand the process of decoding genetic information. The anticodon is a sequence of three nucleotides found on tRNA molecules that complement and bind to the codon on mRNA during protein synthesis.
In this case, we are given the codon GCG. To find the corresponding anticodon, you need to pair the nucleotides with their complementary base. In DNA and RNA, adenine (A) pairs with thymine (T), in DNA, or uracil (U), in RNA, and cytosine (C) pairs with guanine (G).
The anticodon will have a complementary sequence to the codon. So for the codon GCG, the complementary anticodon will be CGC. To find the equivalent RNA anticodon, we just need to replace T with U, so the anticodon for GCG is CGC.
Therefore, the correct answer is D) CGC.
