Question
Chapter 16.4, Problem 3LO
Summary Introduction
To determine: The effect of transcription factors from a distance in the DNA.
Introduction: Transcription factors are also known as sequence-specific DNA binding factors. These factors are proteins that regulate the rate of transcription. These proteins turn on and off a specific gene by binding to a specific DNA sequence.
