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)?

The piwi interacting RNAs (piRNAs) are noncoding RNAs that bind to PIWI proteins to inhibit both the transcription and translation of proteins encoded by Transposable Elements. For instance, the piRISC complexes are expected to inhibit the translation of Transposases that are responsible for the movement of these mobile genetic elements.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

the index of refraction of the second medium is higher. i just took the test trust me !
