antisense RNA

Antisense RNA is a type of RNA molecule that is complementary to a specific messenger RNA (mRNA) in a cell. Its main function is to regulate gene expression by binding to the target mRNA, preventing it from being used to produce proteins. This process can control how much of a particular protein is made, acting as a natural "off switch." Researchers also manipulate antisense RNA to turn genes on or off in studying diseases or developing treatments. Essentially, antisense RNA acts as a regulatory tool that modulates gene activity at the RNA level.
