Question

what does an RNA Induced Silencing Complex do:

- dephosphorylate the G protein

- Bind to an operator

- block or degrade mRNA

- bind to a promoter  

Answer 1

Answer : block or degrade mRNA

Explanation :

The mRNA synthesizes amino acids which forms protein molecules responsible for overall functioning of an organism. RNA induced silencing complex is also known as RISC. The RISC attaches to the single strand RNA (ssRNA). The ssRNA helps in recognizing mRNA for the RISC. So, when the ssRNA recognizes a mRNA, the protein of RISC called as Argonaute becomes activated and cleaves the mRNA leading to gene silencing. This process is also called as RNA interference and is mostly shown by the eukaryotes.
