Chapter 13.3, Problem 31AQP

Summary Introduction

To determine:

If poly-A tail got deleted from rho-independent terminator, but inverted repeats was left; so how it would affect termination.

Introduction:

Rho-factor is a type of prokaryotic protein which causes termination of transcription process. When the RNA forms a hairpin loop structure; rho-factor displaces RNA polymerase and stops transcription process.

Summary Introduction

To determine:

When $\text{RNA}$ polymerase reach this region; what can happen in this condition.

Introduction:

Rho-independent contributes about 50% terminators in prokaryotes. They contain inverted repeats, which are the sequence of nucleotide present on the similar strand that are complementary. In rho-independent terminators, a string of seven to nine adenine nucleotides follows the inverted repeat in the template $\text{DNA}$.
