(a)

Summary Introduction

To predict: Whether dnaB gene’s loss would be lethal to E.coli.

Concept introduction: E.coli consists of many essential genes that are required for the survival of the bacteria and to maintain its growth rate. It also contains the genes to carry out its biochemical pathways and metabolism. A loss in the function of any essential genes would directly affect their growth and survival.

(b)
