RECOMBINANT DNA TECHNOLOGY PART 2
3
Quiz Essay 2 Topics Molecular Topics: 35 points Emphasis: data interpretation, critical thinking with a short answer format ■ Bacterial transformation ■ Plasmid isolation ■ Translation: genetic code table ■ Lac operons: mutational analysis ■ Recombinant DNA technology Genetics’ Topic 15 points ■ Genetic Fine Structure
4
Topics Cloning & Finding cloned genes –Using bacteria –Using viruses Genomic libraries Transgenic plants Transgenic animals Timely topics
5
Technique: Cloning of specific genes or DNA fragments + = restriction enzyme = ligase
6
Cut vector Cut foreign DNA or gene Paste together
7
2 different antibiotic resistant genes Bacteria are now resistant to 2 antibiotics
8
Bacterial cloning using plasmids
9
Cut DNA here & insert foreign DNA
10
Will your transformed colonies with the insert be white or blue?
11
Summary of cloning DNA into a blue/white selection vector
12
Clone into a virus Infect bacteria Identify infected bacteria containing gene –Assume you know the protein sequence Cloning and finding desired clone
13
Bacterial clones and finding desired clone Probe design
14
Genomic library contains all of the organism’s genome
15
Expression Vectors Sources of proteins Expression vectors
16
Transgenic Mice
17
transgene Linear DNA Non-homologous recombination
18
Knockout Mice
19
Phenotype of the knockout mouse gives information on protein function Homozygous knockout G418 gancyclovir
20
Applications of DNA technology Agriculture Drug design Genetic testing Gene therapy
21
Genetic Modified Plants: “GM” Tobacco with luciferase gene from firefly Transgenic plant
22
Tumor Inducing Plasmid
23
Model for making transgenic plants
24
Bt toxin genes (from Bacillus thuringensis) introduced into corn, making it resistant to the European corn borer. Millions acres of corn, cotton, and potatoes bearing Bt toxin are under cultivation.
25
Transgenic Plants In 1996: Soybeans resistant to the weed killer of Round Up.
