The "sides" of the ladder are made of alternating sugar (deoxyribose) and phosphate groups.

DNA () is the hereditary molecule that carries the genetic "instruction manual" for the development, survival, and reproduction of nearly all living organisms . It functions as a stable repository of information, stored in every cell's nucleus, that dictates physical traits and biological functions. Molecular Structure The "sides" of the ladder are made of

The specific sequence of these four bases (A, T, C, and G) creates a biological alphabet that MedlinePlus Genetics compares to letters in a sentence. What is DNA?: MedlinePlus Genetics Molecular Structure The specific sequence of these four

These are the basic building blocks, each consisting of a sugar, a phosphate, and one of four nitrogenous bases. each consisting of a sugar

The National Human Genome Research Institute defines DNA as a , a shape resembling a twisted ladder.
