Brief RNA expression was analyzed from and and siRNAs, piRNAs are thought to silence repetitive sequences at the level of transcription (8). exception of piRNAs; thus, it is possible that other previously unidentified RNAs contribute to the null ES cell mutant phenotype. To further our understanding of Dicer function and the mechanisms by which short… Continue reading Brief RNA expression was analyzed from and and siRNAs, piRNAs are
