Question
Chapter 16, Problem 2IQ
Summary Introduction
To determine: The process of activation of several genes in which transcription occurs at the same time.
Introduction: in molecular biology, the process in which a complementary RNA strand is synthesized from a DNA strand is referred to as transcription. It is the first process of gene expression in organisms.
