The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality ...

What is DNA, and how does it work ... In this analogy nucleotides are the teeth of the zipper; the sugar-phosphate backbone ...

The double-stranded DNA that results from this pattern of bonding looks much like a ladder with sugar-phosphate side supports ... Beyond the ladder-like structure described above, another key ...

Combinations of these atoms form the sugar-phosphate backbone of the DNA -- the sides of the ladder, in other words. Other combinations of the atoms form the four bases: thymine (T), adenine (A ...

The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...
