Nucleotides are the fundamental building blocks of both DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Each nucleotide is composed of three core components: a nitrogeno...

science-history

Rosalind Franklin’s Photo 51 is an X-ray diffraction image of DNA that provided critical evidence for the double helix model. Taken in 1952 by Franklin and her student Raymond...

DNA molecules are built from nucleotides, each consisting of a sugar, a phosphate group, and a nitrogenous base. These nucleotides link into two antiparallel strands that form a...
