Image illustrates DNA, RNA, and protein synthesis. The first two are nucleic acids. A nucleic acid inhibitor is a type of antibacterial that acts by inhibiting the production of nucleic acids. There are two major classes: DNA inhibitors and RNA inhibitors. [1] The antifungal flucytosine acts in a similar manner.
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.
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.

Inhibits DNA and to a lesser extent RNA synthesis, produces single and double strand breaks in DNA possibly by free radical formation.

In molecular biology, RNA polymerase (abbreviated RNAP or RNApol), or more specifically DNA-directed/dependent RNA polymerase (DdRP), is an enzyme that catalyzes the chemical reactions that synthesize RNA from a DNA template.
This bound repressor can reduce transcription of the Lac proteins by occluding the RNA polymerase binding site or by prompting DNA looping. [2] When lactose is present, allolactose binds to the lac repressor, causing an allosteric change in its shape. In its changed state, the lac repressor is unable to bind tightly to its cognate operator.
