Chapter 17: Q. 17.48 (page 600)

Why are there at least 20different tRNAs?

Short Answer

Expert verified

Each codon binds to a distinct anticodon on t RNA, there must be at least 20distinct t RNAs.

Step by step solution

01

Introduction

There are 20amino acids in all.

02

Explanation

There are 20amino acids in all. Each amino acid is represented by a codon (or codons).. There must be at least 20different t RNAs, since each codon binds to a different anticodon on t RNA.
