WebSep 22, 2024 · shRNA is a form of RNA interference (RNAi) technology used to investigate the function of uncharacterized genes. RNAi functions by inhibiting gene function in order to examine the affected processes. It is utilised to characterise biological pathways by identifying interactions between genes, genes, and proteins. WebCRISPR interference (CRISPRi) is a genetic perturbation technique that allows for sequence-specific repression of gene expression in prokaryotic and eukaryotic cells. It was first developed by Stanley Qi and colleagues in the laboratories of Wendell Lim, Adam Arkin, Jonathan Weissman, and Jennifer Doudna. Sequence-specific activation of gene …
