Sensing Ribonuclease H Activity With Dna Nanoswitches, Ruju Trivedi

Biological Sciences

Ribonuclease H (RNase H) is a damage-repair protein and ribonuclease that specifically catalyzes the hydrolysis of RNA in an RNA/DNA duplex and breaks down RNA/DNA junctions. It plays an important role in a variety of biological processes including DNA replication, DNA repair, and transcription. It is also pivotal in anti-HIV drug development and the analysis of cellular processes and has been shown to be a potential therapeutic target for various neoplastic diseases. This thesis discusses a unique assay based on DNA nanoswitches to detect RNase H levels and activity. The assay is based on conformational changes of DNA nanoswitches in …
