Question

The codons UGU and UGC both code for cysteine. The anticodon for UGU is ACA. What is the anticodon for UGC?

A) UCG
B) CGA
C) ACA
D) GCA

Answer 1

The anticodon for UGC is CGA.

Step-by-step explanation:

The anticodon for UGC is CGA. The anticodon is a sequence of three nucleotides on a transfer RNA (tRNA) molecule that is complementary to a specific codon on the messenger RNA (mRNA) during translation. In this case, since both UGU and UGC code for cysteine, the anticodons for both codons would have the same two nucleotides (AC), while the third nucleotide changes:

• The anticodon for UGU is ACA
• The anticodon for UGC is CGA
