Which of the following type of RNA is involved in splicing?
mRNA
sn RNA
r RNA
t RNA
snRNA is involved in RNA splicing i.e removal of introns from hnRNA, regulation of transcription factors or RNA polymerase II and in the maintenance of telomeres. snRNA is a class of small RNA molecules that are found within the nucleus of eukaryotic cells. They are transcribed by RNA polymerase II or RNA polymerase III.
