Contemporary Biology NTSC1111: Basics


What is the hallmark of scholarly literature?

Peer review, reputable Journals, and the scientific process can be duplicated and tested by peers. Bearing this in mind here rae related guides for more information.


Some links to basics from Nature and MEEDLINEPLUS, the layperson database for Medical information on genetics, genetic diseases, etc. It comes from the National Library of Medicine.

Transgenic Animals

Animal biotechnology has been practiced in one form or another since the beginning of the domestication of animals. Many of the previously used tools of animal breeding, genetics, and nutrition have played and will continue to play an important role in the selection, propagation, and management of desirable and economically important characteristics in livestock. In the future, livestock production will rely even more heavily on existing and emerging biotechnological advances to produce our food. Yet, improvements are still needed in product composition and production efficiency, especially in growth, disease resistance, and reproduction. Genetically modified (transgenic) livestock, stem cells, and other emerging biotechnologies will have important roles in producing more and higher quality food derived from livestock.

The production of ‘transgenic animals' is one such biotechnology tool. A transgenic animal is one that has integrated a gene or DNA sequence (a 'transgene'), which has been transferred by human intervention, into the genome of a cell. For the purposes of discussion, a transgenic animal is defined as one that has stably incorporated the transgene into its germ line and is able to pass the transgene on to its offspring.
