Transgenic Animals Online Biology Notes

Applications Of Transgenic Animals.

Transgenic animals online biology notes. Transgenic animals represent unique models that are custom tailored to address specific biological questions. Example- Transgenic rats rabbits pigs sheep etc. Transgenic animals have great importance as 1 to study the normal physiology and development working of genes their regulation etc.

Transgenic animals can be used to produce valuable products. Animals that have had their DNA manipulated to possess and express a foreign gene are known as transgenic animals. The Human Genome Project revealed that the human genome contains only 20000 to 25000 genes.

The foreign gene is constructed using recombinant DNA methodology. They are then exposed to toxic substances and the effects are studied. These are the animals whose genome has been altered by introduction of a foreign gene by manipulation.

Transgenic rats rabbits pigs sheep cows and fish- Over 95 of the transgenic animals are miceBenefits of transgenic animals To study regulation of genes and their action on normal physiology development. In 2003 the project was completed resulting in the sequencing of all human chromosomes. The most important application of this is the introduction of DNA into animal oocytes and embryos either in the study of transient expression or in the generation of transgenic animals.

The development of transgenic animals has been part of biotechnology research which has been expanding rapidly. After injecting the DNA the embryo is implanted into the uterus of receptive females. Transgenic animals are created-To study how genes are regulated and how they affect the normal functions of the body and its development.

The sequence data has led to the estimation that only about 1 percent of. The first transgenic animal was produced in 1983 when genes for human growth hormone were introduced into mice. A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome.
