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 ...

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 ...

Once scientists have zeroed in on a specific segment of DNA, how do they produce enough copies of that segment for their research? In most cases, the polymerase chain reaction, or PCR, is their ...

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 ...

DNA transcription is the vital first step needed for switching on our genes. For a gene to be switched on, it must be acted ...

How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA ...

That 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 ...

The double helix unwinds, and each strand serves as a template for the synthesis of a new complementary strand. DNA polymerase enzymes facilitate this process, ensuring accurate copying of the genetic ...
