miRNA-target interactions

miRNA-target interactions involve tiny RNA molecules called microRNAs (miRNAs) that help regulate gene activity. They do this by binding to specific messenger RNAs (mRNAs), which carry instructions for making proteins. When a miRNA attaches to its target mRNA, it usually prevents the mRNA from producing its protein, effectively turning off or reducing that gene's activity. This process helps cells control which proteins are made, maintaining proper function and responding to changes in the body. Think of miRNAs as regulators that fine-tune gene expression to keep everything running smoothly.
