nuclear RNA


nuclear RNA
The nucleus contains RNA that has just been synthesized, but in addition there is some that seems not to be released, or is only released after further processing, the heterogenous nuclear RNA (hnRNA) and small RNA molecules associated with protein to form snRNPs (small nuclear ribonucleoproteins).
