PhD Title: Investigation of recruitment of EJC and ribosome on transcription sites of Drosophila polytene chromosomes

Supervisors: Dr Saverio Brogna

Gene expression in eukaryotes is much more complicated compare to prokaryotes, as in eukaryotes pre-mRNA processing separate by nuclear envelop from other cytoplasmic events. However research from past and recent evidence suggests that there is link between nuclear and cytoplasmic events and exon junction complex (EJC) is the best model to describe this connecting link. EJC mainly deposit 20-24 nucleotides upstream of spliced junction and guide the mRNA through nuclear pore to the cytoplasm, where they either involve in nonsense mediated decay of mRNA or enhances the translation. I am using Drosophila polytene chromosome to study the recruitment of EJC on transcription sites and investigate their selective association with spliced mRNA.




Studied BSc (Hons) in Microbiology from University of Calcutta, Calcutta, India and MSc Biotechnology from Utkal University, Bhubaneswar, and Orissa, India.


To study post splicing events of mRNA by using Drosophila melanogaster as a model organism.
