This tail is the limiting step for mRNA degradation. “We wondered, why can’t we make multiple tails?” Wang said. “That way, if we lose one, there can be many others.” Wang and her team first ...

The pre-mRNA molecule thus goes through a modification process in the nucleus called splicing during which the noncoding introns are cut out and only the coding exons remain. Splicing produces a ...

A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed ...
