Chapter 15.3, Problem 2CC
Summary Introduction
Transcription process is basically the same in all living organisms. Synthesis of RNA is directed by the template strand. RNA is made by the enzyme RNA polymerase. A single RNA polymerase is used by the bacteria. This enzyme consists of catalytic core that synthesize mRNA and the intrinsic transcription factor subunit represented as sigma (σ).
