Question
Chapter 31, Problem 16P
Interpretation Introduction
Interpretation:
The reason for the recognition of more than one codon by a tRNA molecule should be determined.
Concept introduction:
A tRNA (transfer ribonucleic acid) is a type of RNA, which decodes mRNA into a protein sequence. During the process of translation, tRNAs bind to specific sites on the ribosome. For each codon on mRNA, there is an anticodon on tRNA. Binding of these two RNAs helps in the proper synthesis of proteins.
