Title: Week 11 - Unit 4_5: Control of Gene Expression
Course: Biochemistry

Introduction

All cells have similar set of genes , however in order to function properly , needed proteins must be synthesized at the proper time. All cells control or regulate the synthesis of proteins from information encoded in their DNA. The process of turning on a gene to produce RNA and protein is called gene expression.

Control of gene expression is essential to all organisms. In prokaryotes, cells adapt to environmental changes by changing gene expression. In multicellular eukaryotes, it is critical for directing the development and maintaining homeostasis. In fact, different cell types in a multicellular organism have distinct functions based on the proteins they express. All cells in a multicellular organism share a set of “housekeeping” genes that sustain the cell, but they also express a unique set of proteins that distinguish each cell type Expectation

In this lesson, you will be able to learn different molecular mechanism involved in Gene regulation either in prokaryotes or Eukaryotes.
