What is the function of Small nuclear RNA (snRNA)?Where is it found?
only found in the nucleus of eukaryotes
participate in splicing (removal of introns) mRNA
(from the name, it makes it small since it splices it, and when you think of an RNA that comes of the nucleus, you think of the mRNA)
What is microRNA (miRNA) and what is its function?
It is short non coding
Some of them control the expression or repression of certain genes
(micro, bc micro sd cards can affect the way that a pc works sometimes)
What are Ribozymes? Where are they found?
RNA molecules with enzymatic activity
Found in:They are found in both prokaryotes and eukaryotes
What are the functions of RNA polymerase II
Searches DNA for initiation site.
unwinds the DNA
adds the ribonucleotide and connects them togther to the RNA strand.
Detects termination signals where transcription ends
