Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing ...

Statement 1: DNA synthesis always proceeds in the 5' to 3' direction.

DNA replication, the fundamental process of copying a DNA molecule, is described as semiconservative due to its unique ...

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 ...

A rapid isothermal amplification technique enables pathogen identification and antibiotic resistance detection in low-resource settings. Recombinase polymerase amplification (RPA) is a technique for ...

The latest short science news items from C&EN. Ting F. Zhu, who led the work, says it is a step on the way to creating a mirror version of the so-called central dogma of molecular biology, which ...

A technique can determine for the first time how frequently, and exactly where, a molecular event called 'backtracking' occurs throughout the genetic material (genome) of any species. A technique can ...

When TV shows like CSI: Crime Scene Investigation portray DNA processing in the forensic lab, the results appear instantly with a DNA match wrapping up the case in hours. However, the ...

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 ...
