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). Franklin, Watson, and Crick all published articles ...

these strands twist together to form a double helix. The structure of DNA can also be described as a ladder. The chemical backbones of the ladder are made up of sugar and phosphate molecules that ...

The ability of DNA to store and replicate information stems from its unique double-helix structure. One can imagine it as an elongated, twisted ladder, where each rung represents a unit of genetic ...
