a. True
b. False

Answer 1

Answer:

True

Explanation:

RNA interference is one of the cell's mechanism to regulate gene expression. Two classes of RNA, micro RNA (miRNA) and small interfering RNA (siRNA) are responsible for post transcriptional gene regulation. RNA interference can also help to fight against viral infection. They prevent the transcription of viral gene and in some cases also lead to its degradation by initiating attack from various protein complexes called as ribonucleases.
