Double-stranded DNA consists of two polynucleotides that are arranged such that the nitrogenous bases within one polynucleotide ... were pursuing a definitive model for the stable structure ...

DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

because it carries the same information as its DNA template but is not used for long-term storage. Each ribonucleotide base consists of a ribose sugar, a phosphate group, and a nitrogenous base.

Beginning with the body and ending with the atoms that make up a single DNA base, you'll be able to zoom in to 15 different levels to see DNA's relationship to us as a whole. Along the way you'll ...
