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 ...

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 ...

DNA stands for deoxyribonucleic acid. Nucleic acids are named for where they're found—inside the nuclei of cells—and for the ...

These pairs are called base pairs and they connect the two sugar-phosphate backbones through interactions called hydrogen bonds. In cells, the DNA helix is often overwound, causing a phenomenon ...

DNA and RNA use the same five-carbon sugar, ribose, in their structure. The deoxy- means that on one side of the base pair, there's a place where another base pair can attach itself by way of a ...

Alternatively, a one and zero could be mapped to just two of the four bases. Scientists have said that, if formatted in DNA, every movie ever made could fit inside a volume smaller than a sugar cube.
