Question

Write any two scientific and commercial values of transgenic animals in favour of human beings.

Answer 1

Organisms that have modified genomes are defined as transgenic. Most transgenic bions are produced in the lab for research analysis. For example, “knock-out” rodents are transgenic rodents that have a specific gene of interest.

Complete answer:
Before we find the two scientific and commercial values of transgenic animals, let us know a little more about transgenic animals.
Transgenic animals are animals that have had an unknown gene intentionally injected into their genome. Such animals are most generally produced by the microinjection of DNA into the pronuclei of an inseminate egg which is later inserted into the oviduct of a false-pregnant surrogate parent. This out-turn in the beneficiary animal giving birth to genetically modified progeny. The offspring are then propagated with another transgenic progeny to develop a transgenic line.

A) Two Scientific value of transgenic animals in aid of human being:
- They are utilised in the research of natural science and evolution.
- Transgenic animals are helpful to investigate gene order, their consequence on the usual functioning of the person and its growth.

B) Two Commercial value of transgenic animals in aid of human being:
- Analysis of diseases: Transgenic replicas have been grown for many human diseases like a tumour, rheumatoid arthritis, cystic fibrosis and Alzheimer’s disease.
- Vaccine Protection: Transgenic rodents have been grown to analyse the protection of vaccines before they are being practised on humans.

Additional Information: Transgenesis let the development of elements in animal products, including their quality, the quantity of the total food, and particular nutritional constituents. The transgenic method could produce a means of converting or rising nutritionally favourable traits.

Note: In 1974 Rudolf Jaenisch discovered a transgenic mouse by injecting unknown DNA into its embryo, producing it the world's first transgenic animal. Although, it took another eight ages before transgenic rodents were generated that transferred the transgene to their progeny.
