microRNA And Its Role In Synaptic Regulation

microRNA belong to the non-coding region of the genome. They play a very important role in regulating the other gene activities like synapses. Researchers at Children's Hospital, Boston says that they are involved in the development of the nervous system.// Synapses are the junctions where the bra...
