Craig Mello is one of the two joint winners of the 2006 Nobel prize in physiology or medicine, for the “discovery of RNA interference gene silencing by double stranded RNA.” Ajit Goenka and Hrishikesh Kulkarni caught up with him

What is RNAi?

It is where double stranded RNA inhibits the expression of genes with complementary nucleotide sequences. This phenomenon is proving to be an extraordinary research tool. The realisation that RNAi is a normal means of genetic regulation has opened up a fascinating yet hitherto inconceivable vista in the field of developmental gene regulation. Moreover, RNAi offers tremendous prospects for understanding and manipulating the cellular basis of human diseases.

Did you foresee winning the Nobel prize?

Not really. At first we thought the process of RNAi interesting and we talked about it a lot. But when we found that the process has been conserved across the species we realised that we had hit on something important. We published a …
