RNA Interference Practice Problems

RNA interference shows fascinating promise as a tool in molecular biology for genetic diseases and other conditions like cancer, cystic fibrosis, etc. The mode of action of RNAi is: 

Micro RNAs (mi RNAs) are a class of non-coding RNAs that play important role in the regulation of gene expression. One single miRNA usually targets many genes and one gene might be regulated by multiple miRNAs. The reason for multiple targets is:

Identify the enzyme that cleaves pre-miRNA into an approximately 22 nucleotide miRNA.

Which of the following is a component of the RNA-induced silencing complex (RISC) that contributes to the degradation of target mRNA molecules?

The main distinction between siRNA and miRNA is that the former is _____, while the latter is _____.

One of the potential applications of RNAi technology includes:

Which of the following correctly describes RNAi?

RNA interference (RNAi) is a mechanism by which cells can regulate gene expression. RNAi silences gene expression by binding and degrading:
