And then DNA polymerase moves in and rebuilds the matching half of ... IRA FLATOW: You may recall from watching an animation in some science documentary– and there have been plenty of them– you know ...

During this process, DNA polymerase “reads” the existing DNA strands to create two new strands that match the existing ones. DNA Polymerase enzyme syntheses labeled educational vector ...

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 ...

Taq polymerase is the heat-stable (thermostable) DNA polymerase extracted from the thermophilic bacteria Thermus aquaticus. Its predominant function is in the polymerase chain reaction (PCR ...

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 ...

An enzyme called primase attaches a “primer” to each strand that allows replication to start, then another enzyme called DNA polymerase attaches at the primer and moves along the strand adding new ...

Using cryogenic electron microscopy (cryo-EM), researchers revealed how conformational changes in the viral DNA polymerase alter the virus’s susceptibility to drugs. The new findings further the ...

Now his team has built a mirror version of the 775-amino acid Pfu DNA polymerase, which Zhu says is the largest functional protein to be chemically synthesized to date. In its natural form ...

In the polymerase chain reaction (PCR), one or more sequences of DNA on a genome or gene transcript are selectively replicated, with up to a billion-fold increase in quantity. The method's power is in ...

At the heart of this method lies the Bst DNA polymerase, whose enzymatic properties—such as strand displacement activity, thermostability, and catalytic efficiency—are critical to the success ...

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 ...
