MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key ...

In two separate papers appearing in Proceedings of the National Academy of Sciences, Weninger and Erie looked at both human and bacterial DNA to gain a clearer temporal and structural picture of what ...

In a twist on the question, 'Which came first, the chicken or the egg?', scientists have long faced a similar question about how human adenovirus replicates: 'Which comes first, assembly of the viral ...

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can play ...
