50. The interaction between the codon 5′-AUG-3′ and its corresponding tRNA anticodon involves the alignment

A. 3'-UAC-5'
✓
B. 5'-UAC-3'
C. 3'-AUG-5'
D. 5'-CAU-3'

📝 Explanation

Nucleic acid strands align anti-parallelly; therefore, the 5'-AUG-3' codon pairs with the 3'-UAC-5' (or 5'-CAU-3') anticodon.

📖 Additional Information

  • 3'-UAC-5'
  • 5'-UAC-3'
  • 3'-AUG-5'
  • 5'-CAU-3'

Nucleic acid strands align anti-parallelly; therefore, the 5'-AUG-3' codon pairs with the 3'-UAC-5' (or 5'-CAU-3') anticodon.
