Transgenic Animals Online Biology Notes

Animals that have had their DNA manipulated to possess and express a foreign gene are known as transgenic animals.

Transgenic animals online biology notes. By DAMARIS BENNY DANIEL II Msc. Transgenic animals produced with the purpose of producing better. The dependence of man on animals such as cattle sheep poultry pig and fish for various purposes milk meat eggs wool etc is well known.

In 2003 the project was completed resulting in the sequencing of all human chromosomes. Transgenic mice are developed by injecting DNA into the oocytes or 1-2 celled embryos taken from female mice. Vorticella Lvortexwhirl pool is a microscopic unicellular eukaryotic ciliate.

The commonest species is Vorticella campanula. Clinical cultural and Biochemical diagnosis. A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome.

Example- Transgenic rats rabbits pigs sheep etc. The development of transgenic animals has been part of biotechnology research which has been expanding rapidly. They are then exposed to toxic substances and the effects are studied.

The Human Genome Project revealed that the human genome contains only 20000 to 25000 genes. Organisms containing integrated sequences of cloned DNA transgenes transferred using techniques of genetic engineering to include those of gene transfer and gene substitution are called transgenic animals. Study of insulin-like growth factor.

Transgenic technology has led to the development of. Transgenic animals are created-To study how genes are regulated and how they affect the normal functions of the body and its development. The procedure is the same as that used for testing toxicity of drugs.
