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 ...

is more complicated than it is in some model organisms like yeast, even though it's a very conserved molecular process. There are bells and whistles on the human spliceosome that allow it to ...

This is done by a spliceosome, which also joins the relevant ... To test their hypothesis, the researchers used the model plant Arabidopsis thaliana. They artificially produced plants in the ...

We study minor spliceosome which is a parallel pre-mRNA splicing machinery in the cells of most metazoan organisms. Our main aim is to investigate mechanism and regulation of this nuclear machinery, ...
