This link explains the basics of genetic engineering, gene therapy, transgenic plants and transgenic animals . It also explains how we can use biotechnology in the diagnostics of identifying organism, genes, infectious diseases and genetic disorders. Biotechnology has many helpful applications . Biotechnology is playing a very important role in the Agriculture Industry and is having an impact on the type of food that is being produced. Transgenic livestock are being used in the fields of agriculture and medicine.
Biotechnology has a role in saving animal species from extinction.
Read about the Frozen Zoo and research how biotechnology is playing a role in saving the Cheetah and the Hawaiian Nene . Read these two articles and understand how the nene and cheetah have a very similar problem. The plasmid is then used to import the new DNA strand into the host cell for cloning. The host cell is then cloned so there are many new cells with the foreign DNA in its genetic make-up. The new cells then will listen to the recombinant DNA and produce a foreign protein.
