Natural shape of a dna molecules
Web10 de ago. de 2024 · DNA, or deoxyribonucleic acid, is a molecule consisting of a long series of nucleotides. It serves as the chemical responsible for inherited traits. Lengths of DNA that carry the code for given proteins are known as genes. Nucleotides consist of a sugar, a phosphate group and a nitrogenous base. WebThe scientist Linus Pauling was eager to solve the mystery of the shape of DNA. In 1954 he became a Nobel Laureate in Chemistry for his ground-breaking work on chemical bonds and the structure of molecules and crystals. In early 1953 he had published a paper where he proposed a triple-helical structure for DNA.
