PCR inhibitors are any factor which prevent the amplification of nucleic acids through the polymerase chain reaction (PCR). [1] PCR inhibition is the most common cause of amplification failure when sufficient copies of DNA are present. [2] PCR inhibitors usually affect PCR through interaction with DNA or interference with the DNA polymerase.
[8] beta-Amanitin is also an inhibitor of eukaryotic RNA polymerase II and RNA polymerase III, and as a result, mammalian protein synthesis. It has not been found to inhibit RNA polymerase I or bacterial RNA polymerase. [9] Because it inactivates the RNA polymerases, the liver is unable to repair damage and the cells of the liver die off ...

RNA polymerase 1 (also known as Pol I) is, in higher eukaryotes, the polymerase that only transcribes ribosomal RNA (but not 5S rRNA, which is synthesized by RNA polymerase III), a type of RNA that accounts for over 50% of the total RNA synthesized in a cell.
Inhibits DNA and to a lesser extent RNA synthesis, produces single and double strand breaks in DNA possibly by free radical formation. Germ cell tumours, squamous cell carcinoma, pancreatic cancer, non-Hodgkin's, pleural sclerosing and Hodgkin's lymphoma. Pulmonary toxicity, hypersensitivity, scleroderma and Raynaud's phenomenon. Bortezomib: IV, SC
Polynucleotide Phosphorylase (PNPase) is a bifunctional enzyme with a phosphorolytic 3' to 5' exoribonuclease activity and a 3'-terminal oligonucleotide polymerase activity. [2] That is, it dismantles the RNA chain starting at the 3' end and working toward the 5' end. [1] It also synthesizes long, highly heteropolymeric tails in vivo.
A protein synthesis inhibitor is a compound that stops or slows the growth or proliferation of cells by disrupting the processes that lead directly to the generation of new proteins. [ 1 ] A ribosome is a biological machine that utilizes protein dynamics on nanoscales to translate RNA into proteins
Ribonuclease P (EC 3.1.26.5, RNase P) is a type of ribonuclease which cleaves RNA.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.
