DURHAM, N.C. -- Biochemists have pinpointed how a flaw in DNA that is central to mutations in cancer and aging fools the cellular enzyme that copies DNA. Their finding explains how oxidative DNA ...

If DNA is a book, then how is it read? Learn more about the DNA transcription process, where DNA is converted to RNA, a more portable set of instructions for the cell. The process of transcription can ...

PCR, or Polymerase Chain Reaction, is a revolutionary molecular biology technique that allows for the rapid amplification of specific DNA sequences. It is an essential tool in various fields, ...

As expected, accuracy also depended on whether the DNA polymerase retains a 'proofreading' functionality, which verifies (and if necessary removes) any mismatched nucleotides: a version of the enzyme ...

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) technique ...
