Hi,

Yes you can, because programming is just only how you minimize and solve a particular problem with your logics and Anybody can learn programming, you can concentrate on bio-informatics area so that you can get the full benefit of coding and life science You just need to concentrate for learning programming.

There is a quote for it "There is a will there is a way" mean "If one really wants to do something, one can", so if you have decided to learn something or you have the ability to learn then you can learn anything. Just focus on studies and start learning your programming.

You can take advantage of both worlds (Biology and Computer Science) and start a career in Bioinformatics, which is highly demanded today.  DNA  matching algorithms using complex ATCG LINKS. Maintenance of daily online logs for experiments that can be used and verified by other scientists involving complex and massively random data structures, pattern recognition in electron microscope digital slides, whose parameters can't be set by  software professionals. and on and on.

I believe that development in the field of biology can be accelerated wildly by deploying modern programming techniques by a biology professional.

Hope this helps.

Good luck.
