Silencing of a gene could be achieved through the use of:
a. RNAi only
b. antisense RNA only
c. both RNAi and antisense RNA
d. none of the above
The answer is option (c) both RNAi and antisense RNA
Explanation:
Gene silencing is a method used to turn off specific genes in cells. Two common ways to do this are through RNA interference (RNAi) and antisense RNA technology.RNA interference uses small RNA molecules that attach to the messenger RNA (mRNA) of a gene. When this happens, the mRNA is broken down, and the gene is no longer made into a protein. Antisense RNA technology uses strands of RNA that are the opposite of the target mRNA. These strands bind to the mRNA, stopping it from being translated into a protein or leading to its degradation. Both methods are useful in research and medicine. They help scientists study how genes work and develop treatments for diseases.
