In the context of RNA interference, gene silencing is called __________.

Explain how the expression of a single gene can be quickly, efficiently, and specifically shut down at the transcriptional, posttranscriptional, and posttranslational stages through the coordinated expression of a transcriptional repressor, an miRNA, and a ubiquitin ligase.

siRNAs target a variety of different RNA transcripts for degradation.

Which of the following enzymes are responsible for cleaving and processing miRNAs and siRNAs?

MiRNAs and siRNAs target degradation of RNA transcripts by binding to what?
