The structure of the DNA double helix (type B-DNA). The atoms in the structure are colour-coded by element and the detailed structures of two base pairs are shown in the bottom right.

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.

Sep 13, 2023 · What is the DNA molecule. What does it stand for. Who discovered it. Where is it found. What is it made of. Learn its shape and functions with a diagram.

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 the 5’ end of …

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 components: a …

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 double helix.

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 polymer, a …

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 of a spiral …

Learn how to diagram and label a section of DNA by understanding the structure and components of DNA, including nucleotides, base pairs, and the double helix shape. This article provides a step-by …

Learn about the key parts of the DNA molecule with a detailed diagram, identifying each component and their functions in the structure of genetic material.
