DNA polymerase (DNAP) is a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules. Nucleic acids are polymers, which are large molecules made up of ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

PCR genetic analysis has been in the spotlight since COVID-19, but light is now further facilitating PCR-free methods. Osaka ...

where the enzyme DNA polymerase zips along the single strands starting at the primer to replicate the DNA. The cycle repeats and copies of the original DNA accumulate exponentially. Like any ...

Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a ...

Forensic DNA profiling uses polymerase chain reaction (PCR) to amplify short tandem repeats (STRs), which are highly variable DNA regions, typically with four repeating bases. This variability helps ...

The POLG gene regulates the production of DNA polymerase gamma, an enzyme that copies mitochondrial DNA. Without it, the mitochondria cannot function normally and, as a result, fail to provide the ...

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries ... types of RNA polymerases that can transcribe different types of RNA. RNA polymerase II, shown here, is ...

Rifaximin is a semi-synthetic derivative of rifampin and acts by binding to the beta-subunit of bacterial DNA-dependent RNA polymerase blocking one of the steps in transcription. This results in ...
