Which statement best describes the distinction between the purposes of the two RNAi pathways within the eukaryotic cell?

#Section 3: Genetics, Cellular and Molecular Biology
  1. miRNA-mediated gene silencing represents a back-up pathway should siRNA-mediated gene silencing be unsuccessful at silencing the target dsRNA

  2. siRNA and miRNA-mediated gene silencing pathways must both be active to successfully silence the target dsRNA

  3. miRNA and siRNA-mediated gene silencing represent evolutionary-independent pathways which confer identical silencing mechanisms on the target dsRNA

  4. siRNA-mediated gene silencing represents a cell defence mechanism against exogenous dsRNA; miRNA-mediated gene silencing is an integral gene expression regulation process
