What are microRNAs and why are they important?
MicroRNAs are small, non-coding RNA molecules that play a crucial role in regulating gene expression. They can inhibit or promote the translation of specific messenger RNAs (mRNAs), thereby influencing various biological processes. Their importance lies in their ability to control cellular functions, which is vital for maintaining health and preventing diseases.
