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 ...

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 ...

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 ...

DNA analysis is crucial for identifying individuals and their relatives, using technologies like PCR, electrophoresis, and ...

This gene encodes a protein in mitochondria, called DNA polymerase gamma (pol γ), which is needed to replicate and repair the unique DNA found only inside mitochondria, rather than in the cell nucleus ...

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 ...

View Full Profile. Learn about our Editorial Policies. Polymerase chain reaction (PCR) is a fundamental molecular biology tool that scientists use to amplify and analyze genetic material, such as DNA ...

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 ...

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 ...

Mutations in BRCA2—a gene known to repair damaged DNA and suppress tumor formation—can predict an individual's predisposition ...
