1 EC 3.1.26.5: RNase P is a type of ribonuclease that is unique in that it is a ribozyme â a ribonucleic acid that acts as a catalyst in the same way as an enzyme. 2  Its function is to cleave off an extra, or precursor, sequence on tRNA molecules. RNase A (e.g. , bovine pancreatic ribonuclease A: PDB: 2AAS â) is one of the hardiest enzymes in common laboratory usage; one method of isolating it is to boil a crude cellular extract until all enzymes other than RNase A are denatured.
The antisense strand of DNA is read by RNA polymerase from the 3' end to the 5' end during transcription (3' â 5'). The complementary RNA is created in the opposite direction, in the 5' â 3' direction, matching the sequence of the sense strand with the exception of switching uracil for thymine.ranscription is the first step of gene expression, in which a particular segment of DNA is copied into RNA (mRNA) by the enzyme RNA polymerase.
