The process of translation uses fewer tRNA's than codons

Question

A. when nutrient levels are low, in order to conserve energy

B. because certain tRNAs can recognize multiple codons

C. due to several amino acids sharing certain tRNA's

D. so splicing is employed to remove the excess codons

Answer 1

Wobble base pairing allows tRNAs to recognize multiple codons and thus the requirement of fewer tRNA's than codons.
