madurosomas
Scope note: Organelas en las cuales se producen reacciones de escisión y empalme, que eliminan intrones en las moléculas precursoras de ARN mensajero. El empalmosoma está compuesto por cinco pequeñas moléculas de ARN nuclear (U1, U2, U4, U5, U6) que, trabajando junto a proteínas, contribuyen a plegar de forma adecuada fragmentos de ARN y luego empalmarlos en el mensaje.

Scope note: Organelles in which the splicing and excision reactions that remove introns from precursor messenger RNA molecules occur. One component of a spliceosome is five small nuclear RNA molecules (U1, U2, U4, U5, U6) that, working in conjunction with proteins, help to fold pieces of RNA into the right shapes and later splice them into the message.
