Hi zade, here you are
RNase P is a type of ribonuclease and is currently under heavy research. RNase P is unique from other RNases in that it is a ribozyme – a ribonucleic acid that acts as a catalyst in the same way that a protein based enzyme would. Its function is to cleave off an extra, or precursor, sequence of RNA on tRNA molecules.
Hi birdwithpins, welcome!

One more:
2. Compare the processing of eukaryotic tRNAs, rRNAs, and mRNAs. Which post-transcriptional processing event is unique to the mRNAs?
a. Addition of a methylated guanine at the 5'-end
b. Addition of the CCA sequence by nucleotidyl transferase
c. Removal of extra bases from both the 5' and 3' ends of the RNA
d. Methylation of bases
e. Removal of introns

u know what lily, telomerase is absolutely rite, come to think of it. we all missed d "associated rna " part. RT works on rna but has no Rna as its part

Indidoc1, you are absolutely right. RT is an RNA-dependent DNA polymerase.
