You work in a lab that is studying PIWI proteins. You isolate piRISCs from cells. Based on what you know about how piRISCs silence transposable elements, what enzymatic activities do you anticipate will be associated with the proteins you've isolated (either in the piRISCs themselves, or in proteins that may have been associated with the piRISCs)?
a. Nuclease activityNuclease activity
b. DNA methylaseDNA methylase
c. ProteaseProtease
d. DNA ligaseDNA ligase
e. Kinase
