Question

How is an anticodon conventionally written in terms of directionality?

Options

• UAC without directional notation

• 3' UAC 5'

• 5' UAC 3'

• 5' CAU 3' for reverse complement

Answer 1

An anticodon is written as 3' UAC 5', which is complementary and antiparallel to the codon 5' AUG 3'. This orientation reflects the antiparallel nature of codon-anticodon base pairing during translation.
