Wang award. Ullu received the award, called after an recognized researcher in parasitology internationally, for her laboratory’s work with the protozoan parasite Trypanosoma brucei, which causes African sleeping sickness, to discover a novel mechanism of gene silencing referred to as RNA interference. While focusing on RNA processing and synthesis pathways in T. Brucei, Ullu strike upon the phenomenon of RNA interference , where small, noncoding RNA molecules, than proteins rather, regulate gene expression.It is supplemented with small amounts of seasonal fruits, vegetables, lentil soup, and meat occasionally, fish, and eggs.
