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 ...
1 Denaturation: Double-stranded DNA separates into single ... 6 A combination of highly processive thermostable DNA polymerase and a high-fidelity polymerase with 3′-5′ exonuclease activity helps ...
DNA transcription is the vital first step needed for switching on our genes. For a gene to be switched on, it must be acted ...
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 ...

The bacterium that transformed DNA sequencingThat discovery led to the invention of the polymerase chain reaction, or PCR (as in the PCR tests we took during the pandemic), which enables scientists to select specific DNA fragments and then ...
Exonuclease action of replicative polymerase gamma drives damage-induced mitochondrial DNA clearance
How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA ...
