Chapter 27, Problem 21P

Summary Introduction

To calculate: The DNA required to encode $10$ proteins by bacteriophage $\varphi \times 174$.

Introduction:

The proteins are the macromolecules which are comprised of amino acids linked together by peptide or amide bond. Each of the amino acids is coded by three nucleotide bases. Bacteriophage $\varphi \times 174$ genome include $10$ proteins, which are encoded by 5386 bp.. The size of the proteins and number of amino acid residues is different.

Summary Introduction

To explain: How the size of $\varphi \times 174$ genome can be reconciled with its the protein capacity.

Introduction:

The bacteriophage $\varphi \times 174$ is a single-stranded DNA virus with circular DNA comprised of $\text{5,386 bp}$. The genome encodes for $10$ proteins of varying length. The total number of amino acids in $10$ proteins is $\text{1,928}$.
