Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases. (Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base ...

The double-stranded DNA that results from this pattern of bonding looks much like a ladder with sugar-phosphate side supports and base-pair rungs. Note that because the two polynucleotides that ...

The structure of DNA can also be described as a ladder. The chemical backbones ... between A and T or between C and G. These pairs are called base pairs and they connect the two sugar-phosphate ...

If you can imagine that DNA is a twisted ladder, then each rung of the ladder is a pair of joined molecules, or a base pair. With this section of DNA, one of the base pairs is different from the ...
