Find
the answer for following questions:
a.
In brief describe
about this application (what is it all about?)
Transgenic animals are animals that have been genetically modified through purposely introducing foreign DNA material from another species. This foreign DNA is often times introduced through recombinant DNA technology and must be passed along the germ line so that all of the cells in the body will have the new genetic material.

b.
What are some
benefits of this application?
Some benefits of transgenic animals include contribution to human welfare in three main areas: agriculture, medicine, industry and it a more viable way to create desirable traits in animals compared to selective breeding.

c.
What are some
future improvements which still need to be done to make this application
perfect (limitations)?
Some future improvement or limitations of transgenic animals is that the animals typically have a low survival rate, the procedure is expensive, it is a lengthy process, it can lead to abnormalities in the animal's body and transgenic animals could escape into the natural environment, which is very dangerous for the ecosystem. As you can see, the application of recombinant DNA technology to create transgenic animals still have a lot of future improvements to do in order to make it anywhere near perfect.

d.
What issues
(social, economic, ethical, political or cultural) are currently related to the
use of this application worldwide?
There are some ethical issues of transgenic animals especially concerning those transgenic animals which are purposely flawed to research about diseases on because this will impact the animal's welfare and it also violates the animal's rights. There are also some religious issues but although most are against transgenic animals, there are actually some people in favor of it. In addition to that, transgenic animals also bend the food laws of some religions because even though an animal appears to be one species, it may have a part of a forbidden species in it.
