Question
Chapter 20.4, Problem 20.4Q
Interpretation Introduction
Interpretation:
The function of the promoter sequence in the transcription process has to be determined.
Concept Introduction:
Transcription is the process of synthesis of RNA from a DNA template in the presence of an enzyme called RNA polymerases. It occurs in three different stages namely initiation, elongation, and chain termination. RNA polymerase serves as the enzyme that catalyzes the process of transcription.
