PCR has many research and … WebbPyrosequencing is a method of DNA sequencing (determining the order of nucleotides in DNA) based on the "sequencing by synthesis" principle, in which the sequencing is performed by detecting the nucleotide incorporated by a DNA polymerase.Pyrosequencing relies on light detection based on a chain reaction when pyrophosphate is released. …

WebbDNA polymerases are the enzymes that build DNA in cells. During DNA replication (copying), most DNA polymerases can “check their work” with each base that they add. This process is called proofreading.If the polymerase detects that a wrong (incorrectly paired) nucleotide has been added, it will remove and replace the nucleotide right away, … WebbBIOL230W Week 10 – Replication This week we will focus on the process of replicating DNA that occurs during the S-phase of the cell cycle.
