1) Biotechnology and genetic engineering
Biotechnology may be defined as the use of microorganisms, animal or plant cells or their components to generate products and services useful to human beings. It is the multidisciplinary field including botany, zoology, microbiology, molecular biology, genetics, chemical and process engineering. Medical technology, agriculture and traditional crop breeding are now generally regarded as biotechnology.
The process of genetic engineering is known by many different names such as gene, or DNA manipulation, gene splicing, transgenics and many others. However the underlying processes all have the same aim and that is to isolate single genes of a known function from one organism and transfer a copy of that gene to a new host to introduce a desirable characteristic. In most of the cases vectors are used for the transfer of desired genes. The technique of recombinant DNA technology was developed in 1970, which is a part of genetic engineering. Transgenic microorganisms are produced to obtain pharmaceutical proteins. For example, human insulin is being commercially produced from a transgenic Escherichia coli strain. This strain contains and expresses the human insulin gene. Proteins produced by transgenic cells/organisms are called recombinant proteins. Recombinant proteins are produced only by the specific transgenes that are introduced into them.
Biotechnology and genetic engineering has also given many controversies like GM foods and concerns like environmental safety, consumer choice, intellectual property rights, ethics, food security, poverty reduction, and environmental conservation.

Solution Summary

Biotechnology is the use of microorganisms to generate products and services useful to human beings. It primarily includes techniques of genetic engineering. Feedlot agricultural, on other hand, is an enclosure for feeding, breeding, raising or the holding of livestock or poultry. Aquaculture is the production of aquatic organisms for food, aquarium, or scientific purposes, generally as a commercial venture. Pisciculture is a branch of aquaculture which deals with culture of fish
