Chapter 25.4, Problem 3LO

Summary Introduction

To discuss:

The many ways genes are regulated in eukaryotes.

Given:

Unlike prokaryotic cells, eukaryotic cells can regulate gene expression at many different levels.

Introduction:

At the level of transcription, most of the eukaryotic genes are controlled. The control mechanism is similar to the control mechanism of bacteria. The trans-acting regulatory protein works via the sequence-specific DNA binding to the cis-acting regulatory target sequences. The complexity of gene regulation in the eukaryotes is a result of the presence of many more genes than the prokaryotes.
