Identification Of Key Cellular Organelle Involved In Gene Silencing Could Help In The Development Of Drugs To Fight Diseases

RNA molecules, made from DNA, are best known for their role in protein production. MicroRNAs (miRNAs), however, are short (~22) nucleotide RNA sequences found in plants and animals that do not encode proteins but act in gene regulation and, in the process, impact almost all biological processes - from development to physiology to stress response. Present in almost in every cell, microRNAs are known to target tens to hundreds of genes each and to be able to repress, or "silence," their expression. What is less well understood is how exactly miRNAs repress target gene expression... via Health News from Medical News Today Read More Here..
