11.1: DNA Structure and Function - Biology LibreTexts
Jul 30, 2022 · Our genetic information is coded within the macromolecule known as deoxyribonucleic acid (DNA). DNA belongs to a class of organic molecules called nucleic acids. The building block, or monomer, of all nucleic acids is a structure called a nucleotide. A nucleotide has three parts: phosphate, deoxyribose sugar, and a nitrogen base.

The model for the DNA double helix in 1953 by Jim Watson and Francis Crick marked the start of a new era of molecular genetics and personalized medicine. The model provided a surprisingly simple and clear answer to the fundamental question of how …
Zooming in on DNA Structure - Visible Body
DNA is a macromolecule consisting of two strands that twist around a common axis in a shape called a double helix. The double helix looks like a twisted ladder—the rungs of the ladder are composed of pairs of nitrogenous bases ( base pairs ), and the sides of the ladder are made up of alternating sugar molecules and phosphate groups.
