The nucleus of each of your cells contains all the genetic information (the genome) necessary to build every type of cell and protein in your entire body. Like a complex library in a tiny space 50 ...

In human cells, only a small proportion of the information written in genes is used to produce proteins. How does the cell select this information? A large molecular machine called the spliceosome ...

Preeclampsia is a pregnancy complication with serious risks for mother and child. The only real cure for preeclampsia is delivery. Now, a new mouse study reports that high levels of an mRNA splicing ...

One idea has been that speckles are splicing factories. The splicing reaction would happen inside the speckle, and then the spliced product would leave. “What people found is that’s not what happens,” ...

Biologists have discovered a new type of RNA-splicing regulation that helps to determine which protein-coding exons will be included in messenger RNA transcripts. RNA splicing is a cellular process ...
