Earlier that morning, in the nearby Cavendish laboratory, the two scientists had discovered the structure of deoxyribonucleic acid, or DNA. This discovery changed the world of science and medicine ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding of DNA and RNA structure. Cytosine can be synthesized chemically or isolated from ...
