Is there suppose to be a picture?
I think it is C but i am not completely positive.<span />
<span>siRNA guides the RISC that cleaves the target mRNA. siRNA binds to its target mRNA due to its complementarity.</span> <span>Small interfering RNA (siRNA) has a function in RNA interference, which means it causes gene silencing through repression of transcription. siRNA together with some proteins (like Argonaute) form the RISC. When siRNA recognize the target mRNA it causes degradation of mRNA and thus silencing the gene that encodes that mRNA.</span>
Answer:
The theory of punctuated equilibrium states that evolutionary change is characterised by short periods of rapid evolution followed by longer periods of stasis in which no change occurs. ... To meet this challenge, evolutionary biologists attempt to describe how and why evolutionary changes accumulate over time
Explanation:
The theory of evolution does not describe how species grow into adults.
It explains that populations do change over a period of time, as well as how natural selection plays a big part in evolution. it definitely supports adaptation so that would leave you with C.
hope this helps!
