The twisted ladder metaphorA DNA molecule is often likened to a spiral (or twisted) ladder.In this analogy, the rungs of the ladder are the base pairs (A-T and G-C). The sides of the ladder are the sugar-phosphate backbones of the two strands.This refers to B form DNA.ach strand is composed of nucleotides. A nucleotide consists of a base (a purine or pyrimidine), a sugar (between the other two components) named deoxyribose, and a phosphate group. Nucleotides are linked to each other via phosphodiester bonds, forming a sugar-phosphate backbone to each strand.
