GeneRegulation

(pgs. 309-312)
 * Gene Regulation**

To do this, there are specific proteins, known as repressors, that choose when to activate and deactivate the genes.
 * Gene Regulation is how the DNA decides which genes to express.**

Throughout the masses of bases in the DNA sequence, patterns begin to emerge. These patterns determine specific genes.


 * Genes** are a sequence of DNA that codes for a protein and thus determines a trait.

A group of genes that operate together is known as an **operon**. [|click here to see the segments of a gene]


 * SEE TEXTBOOK PAGE 310 (figure 12-13) TO DETERMINE HOW REPRESSORS HELP IN GENE ACTIVATION IN BACTERIA CELLS

EUKARYOTIC GENE REGULATION** (pg 311)**:** more complex than that of prokaryotes, and are usually controlled individually. Because of this, operons are usually not found in eukaryotic genes.

-happens during embryonic development. -controled by **hox genes**, or "master control genes"
 * Differentiation** (pg 312)**:** the specialization in structure and function of genes.
