(Nanowerk Spotlight) Hydrogen bond base pairing forces are essential for the mechanisms associated with DNA stability. Despite attracting great research attention, this fundamental interaction has ...

Molecular models are a tried-and-tested tool for teaching chemistry to students of all ages. By enabling users to visualize the three-dimensional structure of a molecule and how its atoms are arranged ...

In the search for the chemical origins of life, researchers have found a possible alternative path for the emergence of the characteristic DNA pattern: According to the experiments, the characteristic ...

There are four bases: Adenine and Guanine (purines); Cytosine and Thymine (Pyrimidines). Purines have two carbon-nitrogen rings while pyrimidines have a single carbon-nitrogen ring. Thus, there are ...

A team of researchers has found that transcription factors have a tendency to bind strongly to 'mismatched' sections of DNA, i.e. sections of the genome that were not copied correctly. The strong ...

A new type of DNA editing enzyme, developed in HHMI Investigator David Liu’s lab, lets scientists directly and permanently change single base pairs of DNA from A•T to G•C. The process could one day ...

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Beam Therapeutics, a biotechnology company developing precision genetic medicines through base editing, today announced new preclinical data for the company’s ...
