Researchers harness the power of the world’s most advanced supercomputers to simulate the inner workings of cellular ...

Scientists have provided the most detailed account yet of the earliest stages of DNA replication, an essential process for ...

In 1953, Francis Crick and James Watson described the molecular shape of DNA as a "double helix." Double-stranded DNA is composed of two linear strands that run opposite to each other, known as ...

Not all DNA is in the double helix form described in textbooks since the 1950’s. Quadruple helix DNA, also known as G-quadruplex DNA, was identified in the human genome several decades ago, and ...

Franklin, working mostly alone, found that her x-ray diffractions showed that the "wet" form of DNA (in the higher humidity) had all the characteristics of a helix. She suspected that all DNA was ...

This process takes place in the nucleus and occurs in a series of stages. The two strands of the DNA helix are unzipped by breaking of the weak Hydrogen bonds between base pairs. This unwinding of ...
