Lesson Overview

Lesson Overview. 13.4 Gene Regulation and Expression. THINK ABOUT IT . Think of a library filled with how-to books. Would you ever need to use all of those books at the same time? Of course not. Now picture a tiny bacterium that contains more than 4000 genes.

How and Why Genes Are Regulated

How and Why Genes Are Regulated. Four of the many different types of human cells: They all share the same genome. What makes them different?. Gene Expression. Genes are expressed as traits Traits are proteins or result from reactions which are regulated by proteins, such as enzymes.

Control of Gene Expression

Control of Gene Expression. Chapter 16 Genes and Development. Proteins can determine the DNA sequence by binding the major groove of DNA. Proteins binding the minor groove cannot determine the exact sequence of bases. Prokaryotic gene regulation Lac Operon. Prokaryotic gene regulation

Gene Regulation

Gene Regulation. Remember! All of your cells contain the exact same DNA. Your nerve cells do not look like or act like skin cells, so do they use the same genes? NO!. Gene Regulation. Genes are to be turned on/off based on whether they will be used or not!
