Biotechnology and Healthcare-
Most developments in biotechnology originated for their potential applications in health care of both human and animal, but primarily the former. And it is in this sector that the contributions of biotechnology are more frequent, more notable and more rewarding (both financially and psychologically).

It is difficult to summarise the whole gamut of contributions in a text of limited space; these could be grouped under the following broad heads:

(i) disease prevention,

(ii) disease detection,

(iii) therapeutic agents,

(iv) correction of genetic diseases,

(v) fertility control and

(vi) forensic medicine. It is aimed to highlight the major developments under each of these categories by citing appropriate examples.
