Biochemistry and plant biotechnology final year student planning to do postgrad in bioinformatics. Is it possible without pragramming knowledge ? How do I start

Good day.

I need advice here!
I am an undergraduate final year student in biochemistry and plant biotechnology. I am planning to do bioinformatics in my postgraduate, having no knowledge of pragramming-is it a good idea to start straight with bioinformatics or should I start with pragramming courses first?And are there good career opportunities in bioinformatics?

Thanks
