How does DNA help us in medicine?

QOTD

Mr.DunnumDNA TECHNOLOGY

Refers to the set of techniques for combining genes from different sources in vitro( in a test tube) and transferring this DNA into a cell so it can be expressed.

RECOMBINANT DNA TECHNOLOGY

DNA technology is changing the pharmaceutical industry

DNA technology-Is widely used to produce medicines and to diagnose diseases

WHY IS DNA TECHNOLOGY SO IMPORTANT?

The use of living organisms to do practical tasks.

Examples:The use of microorganisms to make cheese

and wineSelective breeding of livestock and cropsProduction of antibiotics from microorganismsProduction of monoclonal antibodies

BIOTECHNOLOGY

To find practical applications of DNA techniques for the improvement of human health and food production

Examples:Medical uses.

Diagnosis of disease Making vaccines and

other pharmaceutical products

GOAL OF BIOTECHNOLOGY

Therapeutic hormones

In 1982, humulin, human insulin produced by bacteria

Became the first recombinant drug approved by the Food and Drug Administration

MEDICINES

Gene therapy may someday help treat a variety of diseases

Gene therapyIs the alteration of an affl icted

individual’s genes

GENE THERAPY

Insert normal geneinto virus

Infect bone marrowcell with virus

Viral DNA insertsinto chromosome

Bone marrowcell from patient

Inject cellsinto patient
