Chapter 25, Problem 22P

Interpretation Introduction

(a) Interpretation:

The changed part of the tRNA molecule should be identified.

Concept Introduction:

A mutation is referred to as nonsense mutation when the codon for a specific amino acid has been changed to stop the codon and this leads to the termination of the translation process of the polypeptide chain.

Interpretation Introduction

(b) Interpretation:

The effect of this on translation globally within the cell should be determined.

Concept Introduction:

A mutation is referred to as nonsense mutation when the codon for a specific amino acid has been changed to stop the codon and this leads to the termination of the translation process of the polypeptide chain.

Interpretation Introduction

(c) Interpretation:

The reason why mutation do not have deleterious effects should be explained.

Concept Introduction:

A mutation is referred to as nonsense mutation when the codon for a specific amino acid has been changed to stop the codon and this leads to the termination of the translation process of the polypeptide chain.
