Te molekule so pomembne pri RNA biogenezi in pri kemijski modifikaciji rRNA, tRNA in snRNA. <br /> <br /> == SnRNA in snRNP ==<br /> SnRNA skupaj z molekulami proteinov tvori &#039;&#039;&#039;male jedrične [[ribonukleoprotein]]ske delce&#039;&#039;&#039; (snRNP - small nuclear ribonucleoprotein). To je RNA proteinski kompleks, ki katalizira reakcije izrezovanja nekodirajočih zaporedij (intronov) iz nemodeficirane pre-mRNA, tako da se lahko kodirajoča zaporedja (eksoni) povežejo v funkcionalno mRNA. <br /> <br /> == Delitev ==<br /> SnRNA delimo v dva razreda glede na skupne značilnosti zaporedja in povezane proteinske faktorje. Prvi razred &#039;&#039;&#039;Sm RNA&#039;&#039;&#039; je prepisan z RNA polimerazo II. Poznamo več vrst snRNA razreda SmRNA, ki so U1, U2, U4, U4atac, U5, U7, U11, in U12. Drugi razred &#039;&#039;&#039;Lsm RNA&#039;&#039;&#039; se prepisuje z RNA polimerazo III in nikoli ne zapusti jedra, za razliko od Sm RNA. Poznamo le dve vrsti snRNA razreda Lms RNA in to sta U6 in U6atac.<br /> <br /> == Viri ==<br /> <br /> Boyer, R. (2005). Mali jedrni ribonukleinski delci (snRNP). Temelji biokemije (str. 267-268).
