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 ...

The process is called the DNA polymerase chain reaction (PCR). (If it sounds familiar, it's because PCR-powered COVID testing ...

Once transcription is initiated, the DNA double helix unwinds and RNA polymerase reads the template strand, adding nucleotides to the 3′ end of the growing chain (Figure 2b). At a temperature of ...

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 ...

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

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 ...

Free DNA nucleotides – needed to form the new strands. DNA polymerase – an enzyme that adds new nucleotides to a growing strand of DNA. Primers – A primer is a short strand of nucleotides th ...
