Most certainly yes! In fact, a new field has emerged out of biology and chemistry which is Computational Biology, which is a heavy Biology as well as Computer oriented field. As a computational biologist, you'll be expected to run queries on databases like FASTA, Pronet and many like these. You'll also be expected to learn light Python programming as most of the computations for research happen in Python. So, in general there is very much scope of Computers after doing BSc in Biology or Chemistry.

Hope I have answered your question. All the best!
