DNA Technology
2
There are currently many types of Biotechnology that are being used across the world What does Biotechnology mean???
3
We will analyze 5 types: Cloning Recombinant DNA Gel Electrophoresis Genetic Engineering Human Genome Project
4
Cloning Cloning- is the process of using specialized DNA technology to produce multiple, exact copies of a single gene or other segment of DNA to obtain enough material for further study In 1997, Dolly was cloned
6
Recombinant DNA Recombinant DNA is DNA that has been created artificially. DNA from two or more sources is incorporated into a single recombinant molecule. http://www.dnalc.org/resources/3d/20- mechanism-of-recombination.html
7
Recombinant DNA is the general name for taking a piece of one DNA, and combining it with another strand of DNA. Thus, the name recombinant! Recombinant DNA is also sometimes referred to as "chimera.“ By combining two or more different strands of DNA, scientists are able to create a new strand of DNA. The most common recombinant process involves combining the DNA of two different organisms.
8
Below are some of the areas where Recombinant DNA will have an impact: Better Crops (drought & heat resistance) Recombinant Vaccines (ie. Hepatitis B) Prevention and cure of sickle cell anemia Prevention and cure of cystic fibrosis Production of clotting factors Production of insulin Production of recombinant pharmaceuticals Plants that produce their own insecticides Germ line and somatic gene therapy
9
Gel Electrophoresis Gel electrophoresis is a procedure for separating a mixture of molecules (DNA) through a stationary material (gel) in an electrical field.

Genetic Engineering Genetic engineering is a laboratory technique used by scientists to change the DNA of living organisms. GE uses Recombinant DNA technology to get a desired product Ex: golden rice

Human Genome Project Completed in 2003 identified all the approximately 20,000- 25,000 genes in human DNA
