Annotation: This article discusses the discovery of the double helix structure of DNA, its main components, and the biological significance of its structure. The author briefly discusses the contributions of scientists such as James Watson, Francis Crick, Rosalind Franklin, and Erwin Chargaff to the understanding of the structure of DNA. Also, important aspects such as the chemical structure of DNA, antiparallel strands, base pairing, and right-handed helix are explained in a simple and understandable way. The article is a useful source of information for students who want to understand the basics of molecular biology.

Keywords: DNA, double helix, Watson and Crick, Rosalind Franklin, Chargaff's rule, nucleotide, antiparallel, base pairing, molecular biology, X-ray crystallography.
