Biology Chapter 12 Section 5 Gene Regulation

Objectives ______________a typical gene _________how lac genes are turned off and on __________how most eukaryotic genes are controlled ________gene regulation to development Describe Explain Relate

An _____________is a group of genes that operate together. In E. coli, these genes must be turned on so the bacterium can use lactose as food. Therefore, they are called the lac operon. operon

The lac genes are turned off by repressors and turned on by the presence of lactose. Many genes are regulated by repressor proteins. Some genes use ________________that speed transcription. Sometimes regulation occurs at the level of protein synthesis. proteins

Eukaryotic Gene Regulation Operons are generally ______________in eukaryotes. Most eukaryotic genes are controlled individually and have regulatory sequences that are much more complex than those of the lac operon. not found

Development and Differentiation As cells grow and divide, they undergo_________________, meaning they become specialized in structure and function. __________________control the differentiation of cells and tissues in the embryo. differentiation Hox genes
