GlossarymicroRNAs (miRNAs)

small RNA molecules that regulate gene expression

MicroRNAs (miRNAs) are small, non-coding RNA molecules, typically about 22 nucleotides long, that play a crucial role in regulating gene expression. They work by binding to messenger RNA (mRNA) molecules, leading to their degradation or inhibiting their translation into proteins, thus influencing various biological processes, including development, cell differentiation, and disease.
