Genetic engineering is a very broad discipline that is best broken down into its areas of practical application in order to be most easily understood. At the highest level, genetic engineering can be sub-divided into the creation of genetically modified (GM) plants, animals and micro-organisms, as well as the application of genetic engineering in healthcare, otherwise known as genetic medicine. In turn, genetic medicine may be usefully sub-divided into the fields of genetic testing, pharmacogenetics, and gene therapy.

You should opt for Masters in biology.

Dear,
For UPSC, you need to be graduate first. Complete your graduation first in the discipline of your interest. I detest start preparing for logical questions, basic maths and General knowledge.

Hello Aniket,
It takes 5 years to become a zoologist ( 3 years to complete B.Sc. in Zoology and 2 years to complete M.Sc. in Zoology). However, if you pursue an integrated course in zoology (B.Sc + M.Sc), you can become a zoologist in 4 years. This saves an year of your career. However, there are very few colleges providing integrated courses. Hence, the seats are less and competition is very tough.
