When most genes are transcribed, the nascent RNAs they produce are not quite ready to be translated into proteins - they have to be processed first. One of those processes is called splicing, a mechanism by which non-coding ...

In biology, getting rid of stuff can be just as important as making it. A buildup of cells, proteins, or other molecules that are no longer needed can cause problems, so living things have evolved several ways to clean house.

The totality of RNA molecules in an organism at any one time is the product of a delicate dance. Genes must be "turned on," or expressed, in order to turn DNA into RNA and then that RNA into proteins that accomplish an organism's ...

(Phys.org)—The nucleic acid RNA is an essential part of the critical process by which the cells in our bodies manufacture proteins. But noncoding RNAs also exist whose sequences, while not converted into proteins, play ...

(PhysOrg.com) -- To find our way, we use maps. Cells use "chemical maps" to find the way: they orient themselves by following concentration gradients of attractants or repellants. David H. Gracias and a team at Johns Hopkins ...
