Dear,

There is no college in DU offering biotechnology at undergraduate level.However, there are multiple other similar professional honors courses in various colleges such as:

1. Biomedical science
2. Microbiology
3. Food technology
4. Biochemistry
5. Life sciences
6. Biological sciences

The seats available for each college is different, hence I would recommend to go through this website for details about all colleges and their seats: https://university.careers360.com/articles/du-seats

Hope this helps!
