CloningCloning

Cloning- is the process of using Cloning- is the process of using specialized DNA technology to produce specialized DNA technology to produce multiple, exact copies of a single gene or multiple, exact copies of a single gene or other segment of DNA to obtain enough other segment of DNA to obtain enough material for further study material for further study

In 1997, Dolly was clonedIn 1997, Dolly was cloned

Recombinant DNARecombinant DNA

Recombinant DNA is DNA that has been Recombinant DNA is DNA that has been created artificially.created artificially.

DNA from two or more sources is DNA from two or more sources is incorporated into a single recombinant incorporated into a single recombinant molecule.molecule.

Recombinant DNA is the general name for taking a Recombinant DNA is the general name for taking a piece of one DNA, and combining it with another strand piece of one DNA, and combining it with another strand of DNA. Thus, the name recombinant! of DNA. Thus, the name recombinant!

Recombinant DNA is also sometimes referred to as Recombinant DNA is also sometimes referred to as "chimera.“"chimera.“

By combining two or more different strands of DNA, By combining two or more different strands of DNA, scientists are able to create a new strand of DNA. scientists are able to create a new strand of DNA.

The most common recombinant process involves The most common recombinant process involves combining the DNA of two combining the DNA of two different organisms. different organisms.

Below are some of the areas where Below are some of the areas where Recombinant DNA will have an impact:Recombinant DNA will have an impact:

Better Crops (drought & heat resistance) Better Crops (drought & heat resistance) Recombinant Vaccines (ie. Hepatitis B) Recombinant Vaccines (ie. Hepatitis B) Prevention and cure of sickle cell anemia Prevention and cure of sickle cell anemia Prevention and cure of cystic fibrosis Prevention and cure of cystic fibrosis Production of clotting factors Production of clotting factors Production of insulin Production of insulin Production of recombinant pharmaceuticals Production of recombinant pharmaceuticals Plants that produce their own insecticides Plants that produce their own insecticides Germ line and somatic gene therapy Germ line and somatic gene therapy

Gel ElectrophoresisGel Electrophoresis

Gel electrophoresis is a procedure for Gel electrophoresis is a procedure for separating a mixture of molecules separating a mixture of molecules (DNA) through a stationary material (DNA) through a stationary material (gel) in an electrical field.(gel) in an electrical field.
