Chapter 26, Problem 16E

Summary Introduction

To explain: The biological function of linking of 5ʹ end of regulatory RNAs to 3ʹ-OH group of adenosine residue of NAD⁺ and how the activity of a modified RNA might reflect the cell’s overall metabolic activity.

Introduction: Bacterial RNA polymerases initiate transcription with the adenosine residue of NAD⁺. Bacterial regulatory RNAs are a group of heterogenous molecules such as riboswitches. They act to modulate various physiological responses.
