Question

In the first stage of RNA interference, a ___________________ RNA precursor is cleaved by the ____________ enzyme
The cleaved molecules are approximately _____ (insert number) bases in length and are called __RNA if the RNA
originated from a virus or __RNA if the RNA was of endogenous origin (if the RNA precursor was produced artificially, it’s
called __RNA). The cleaved RNA is then separated into __________________ RNA, which then binds to the ribonuclease
complex called _____________. The short RNA molecules can then target the complex to __RNA with a
__________________ sequence, which is then cut at that site.

3. 20-25 base

4. interference

5. natural

6. exogenous

7. Single stranded RNA

8. Ribonucleo interference RNA complex

9.

Interference

10. interferring complementary.
