Hey Shruti, Cut off for GATE in Bio-Technology was about 27.9 marks for general category and 25 marks for OBC.

Whereas last to last year it was about 38.9 marks for general category and 35 marks for OBC category.

As expected this year also cutoff trend will remain the same as for last year that is you can expect the cut off to be between 25 to 30. Nothing can be said clearly and these are assumptions only based on the previous year trends.

You can refer to the following link for previous year cutoffs:

Hope this helps.
