microRNA

MicroRNA (miRNA) are tiny molecules in our cells that play a crucial role in regulating gene expression. They are like tiny switches that help determine how much of a specific protein is made by binding to messenger RNA (mRNA), which is the blueprint for building proteins. By influencing these proteins, microRNA can affect various biological processes, including development, cell growth, and response to stress. Abnormal levels of miRNA are linked to diseases, including cancer, making them an important area of research in understanding health and disease.
