Chapter 22, Problem 22.70EP

(a)

Interpretation Introduction

Interpretation:

The validation of the given statement that the three phases of protein synthesis are transcription, translation and transformation has to be stated.

Concept Introduction:

The process by which generation of new proteins in a cell takes place is known as protein synthesis.  It consists of two phases, that is, transcription and translation.  DNA molecules undergo transcription to yield RNA which in turn undergoes translation to form proteins.

(b)

Interpretation Introduction

Interpretation:

The validation of the given statement that translation precedes transcription in protein synthesis has to be stated.

Concept Introduction:

The process by which generation of new proteins in a cell takes place is known as protein synthesis.  It consists of two stages, that is, transcription and translation.  DNA molecules undergo transcription to yield RNA which in turn undergoes translation to form proteins.

(c)

Interpretation Introduction

Interpretation:

The validation of the given statement that RNA is the starting material for protein synthesis has to be stated.

Concept Introduction:

The process by which generation of new proteins in a cell takes place is known as protein synthesis.  It consists of two stages, that is, transcription and translation.  DNA molecules undergo transcription to yield RNA which in turn undergoes translation to form proteins.

(d)

Interpretation Introduction

Interpretation:

The validation of the given statement that the transcription phase of protein synthesis converts DNA to RNA has to be stated.

Concept Introduction:

The process by which generation of new proteins in a cell takes place is known as protein synthesis.  It consists of two stages, that is, transcription and translation.  DNA molecules undergo transcription to yield RNA which in turn undergoes translation to form proteins.
