Presentation on theme: "Prokaryotic Gene Regulation"— Presentation transcript:

1 Prokaryotic Gene Regulation
Proteins that bind to DNA can control transcription What does this allow for? Act as a light switch- turn genes on or off Operon- group of genes regulated together

2 E. Coli and the Lac Operon
Only turns on lac operon when needed

3 Promoters and Operators
Promoter- helps RNA polymerase to bind to DNA Operator- site where a repressor can bind

4

5 Eukaryotic Gene Regulation
Transcription factors- control expression of genes Why so complex? Cell specialization

6 Daily Warm-Up Jan. 10th How many chromosomes do humans have?
HW: Read 13.4 Begin working on Punnett squares Study for quiz on Monday Turn in: Lorenzo’s Oil movie sheet if haven’t already

7 Gene Regulation and Development
Early in life certain genes turned on and off Allows for differentiation What is this again?

8 Homeotic Genes Regulation of what develops where Homeobox genes
Code for transcription factors that control developmental genes

9

10 Sex Chromosomes Determine gender of individual XX= Female, XY= Male
Autosomes- other chromosomes

11 Sex-linked Inheritance
Genes can be carried on the sex chromosomes Sex-linked disorders Adrenoleukodystrophy Hemophilia Color-blindness Duchennes Muscular dystrophy

12 Sex-linked Punnett square
