Molecular Basis of Inheritance

[DIAGRAM: Base pairing between an mRNA codon 5' UAC 3' and a tRNA anticodon 3' AUG 5', with complementary bases U-A, A-U, and C-G and 5' and 3' ends labeled.] Against the codon 5' UAC 3', what would be the sequence of anticodon on tRNA?

  1. (A)5' GUA 3'
  2. (B)5' AUG 3'
  3. (C)5' ATG 3'
  4. (D)5' GTA 3'

The NCERT line that answers it

Concept-grounded
