TYPES OF BIOTECHNOLOGY Microbial Biotechnology – manipulation
of microorganisms such as yeast and bacteria Create better enzymes More efficient decontamination processes
for industrial waste product removal Used to clone and produce large amounts
of important proteins used in human medicine

Foods with higher protein or vitamin content
Drugs developed and grown as plant products

Antibodies Animals as important models in basic
research Gene “knockout” experiments Design and testing of drugs and genetic
therapies Animal cloning

1. Cloning requires an egg cell, and an adult donor cell. The (unwanted) chromosomes are removed from the egg cell and discarded. The nucleus, containing the DNA to be cloned, is removed from the donor cell. 2. The donor nucleus is inserted into the empty egg cell, a process called somatic cell nuclear transfer (SCNT). Afterwards the egg contains a full (adult) set of chromosomes as if it had been fertilised normally. 3. A pulse of electricity, or a chemical 'shock', kick-starts the development process, and the embryo begins to grow. 4. Cell division begins. The subsequent development of the embryo depends upon how successfully the donor nucleus has 're-programmed' the egg.

TYPES OF BIOTECHNOLOGY Forensic Biotechnology
DNA fingerprinting Inclusion or exclusion of a person from
suspicion Paternity cases Identification of human remains Endangered species Tracking and confirmation of the spread of
disease

TYPES OF BIOTECHNOLOGY Bioremediation
The use of biotechnology to process and degrade a variety of natural and manmade substances
Particularly those that contribute to pollution For example, bacteria that degrade
components in crude oil
1989 Exxon Valdez oil spill in Alaska

TYPES OF BIOTECHNOLOGY Aquatic Biotechnology
Aquaculture – raising finfish or shellfish in controlled conditions for use as food sources
30% of all fish consumed by humans worldwide Genetic engineering
Disease-resistant strains of oysters Vaccines against viruses that infect salmon and
other finfish Rich and valuable sources of new genes,
proteins and metabolic processes with important applications for human benefits
Marine plankton and snails found to be rich sources of antitumor and anticancer molecules
