Jul 23, 2025 · The diagram of DNA structure depicts a double helix structure, with nucleotides forming the sugar-phosphate backbone and nitrogenous bases pairing via hydrogen bonds.

Chromosomal DNA consists of two DNA polymers that make up a 3-dimensional (3D) structure called a double helix. In a double helix structure, the strands of DNA run antiparallel, meaning …

DNA and RNA are made up of monomers known as nucleotides. The nucleotides combine with each other to form a polynucleotide, DNA or RNA. Each nucleotide is made up of three …

Most DNA is found inside the nucleus of a cell, where it forms the chromosomes. Chromosomes have proteins called histones that bind to DNA. DNA has two strands that twist into the shape …

Learn about the structure of a DNA molecule with a labeled diagram, including the base pairs, sugar-phosphate backbone, and double helix shape.

A molecule of DNA consists of two strands that form a double helix structure. DNA is a macromolecule consisting of two strands that twist around a common axis in a shape called a …

Nov 28, 2025 · In 1953 James Watson and Francis Crick, aided by the work of biophysicists Rosalind Franklin and Maurice Wilkins, determined that the structure of DNA is a double-helix …
