Q. If the base sequence of a codon in mRNA is 5’ – AUG – 3’, the sequence of tRNA pairing with it must be
A) 5’ – UAC – 3’
B) 5’ – CAU – 3’
C) 5’ – AUG – 3’
D) 5’ – GUA – 3’
Explanation
The reading frame of an anticodon is opposite to that of codon. Thus, if the base sequence of mRNA codon is 5’ – AUG – 3’, its complementary anticodon will be 5’ – CAU – 3’.
