Chapter 26, Problem 9P

Interpretation Introduction

(a) Interpretation:

Partial diploid forms of E.coli were creating, each of which contained a complete lactose operon at its normal chromosomal site and the regulatory sequences only (lacI, P, lacO) on a plasmid. Predict the effect of each mutation on the activity of β-galactosidase before and after the addition of inducer. Use -, +, or, ++ to indicate approximate activity levels. the basis for each of your predictions should be explainedbriefly.

Concept Introduction:

E. coli is a haploid organism but E. coli containing two copies of certain genes and is partial diploid. This partial diploid E. coli cell contains a large circular genome with lac operon genes and a small circular plasmid containing regulatory genes (lacI, P, lacO).
