This process enables a single gene to produce multiple proteins; over evolutionary timescales, splicing can also change the size and content of genes and proteins, when different exons become included ...

Shown is the splicing pathway. The pre-messenger RNA (pre-mRNA) has exons (blue) and introns (pink). The spliceosome (not shown) was known to catalyze two chemical reactions (black arrows) in a ...

Researchers at Baylor College of Medicine and collaborating institutions have discovered that a protein called hnRNPM helps protect the integrity of the process cells use to make proteins. The protein ...

Each mRNA transcript contains coding regions, known as exons, and noncoding regions, known as introns. They also include sites that act as signals for where splicing should occur, allowing the cell to ...

The origins of introns and their evolutionary role remain unclear. In the November 6 Proceedings of the National Academy of Science, Alexei Fedorov and colleagues describe the use of a computer ...

DNA is the genetic code that provides the biological instructions for every living species, but not every bit of DNA helps the species survive. Some pieces of DNA are more like parasites, along for ...
