Dicer was given its name in 2001 by Stony Brook PhD student Emily Bernstein while conducting research in Gregory Hannon's lab at Cold Spring Harbor Laboratory. Bernstein sought to discover the enzyme responsible for generating small RNA fragments from double-stranded RNA. Dicer's ability to generate around 22 nucleotide RNA fragments was discovered by separating it from the RISC enzyme complex after initiating the RNAi pathway with dsRNA transfection. This experime… WebThe discovery of RNAi in 1998 led to an almost immediate revolution in the investigation of gene function. As long as a gene's sequence is known, one can quickly synthesize dsRNA corresponding to that sequence to inhibit or "knock down" that gene's function. What is similar between siRNAs and miRNAs?
