Dear student,

Both PCM and PCB students can study Biotechnology. In B.Sc, B.E and B. Tech Biotechnology specialization is there. This field has good scope and has decent future. So if you belong to PCM also you can study this course. But if you study PCB it will be easy for you in understanding the topics.
