snRNP (pronounced snurp)
n : Small nuclear ribonucleoprotein. A compound comprising small nuclear RNA and nuclear protein, that is involved in the post-transcriptional processing of mRNA, especially the removal of introns. snRNPs are a major component of spliceosomes.
  When I first learned about snurps in molecular biology class many years ago, I thought they were pretty cool. DNA contains subsequences (introns) that are evidently not needed. The snurps remove these introns from pre-mRNA (which is transcribed directly from the DNA) and splice what remains together to produce mRNA, which is then translated into proteins. Thus we can think of the snurps as being responsible for "cutting out the crap."
