What's the difference between mRNA and pre-mRNA? It's all about splicing of introns. See how one RNA sequence can exist in nearly 40,000 different forms. Next, the snRNPs U2 and U4/U6 appear to ...

A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing is a ...

Identifying splice sites is also important in annotating genomes, which involves identifying which parts of our DNA are functional and what roles they play in the body. One familiar application of ...

In human cells, only a small proportion of the information written in genes is used to produce proteins. How does the cell ...

The sections of DNA (or RNA) that code for proteins are ... thus goes through a modification process in the nucleus called splicing during which the noncoding introns are cut out and only the ...
