This means that one strand's sugar-phosphate chain ... to argue that DNA actually takes the form of a double helix, a ladder-like structure that is twisted along its entire length (Figure 6).

DNA replication is the process by which the DNA molecule makes an exact copy of itself during cell division. The double helix unwinds, and each strand serves as a template for the synthesis of a new ...

so that matching base pairs interlocked in the middle of the double helix to keep the distance between the chains constant. Watson and Crick showed that each strand of the DNA molecule was a ...

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 ...

Researchers at the Chambers University of Technology have discovered that water is why DNA strands are wrapped around each other and have a helix shape. Understanding how DNA repairs itself could ...
