DNA Structure

DNA, or deoxyribonucleic acid, is the molecule that carries genetic instructions for the development, functioning, growth, and reproduction of all known living organisms and many viruses. Its double-helix structure, discovered by James Watson and Francis Crick, allows it to store and transmit genetic informat...

In 1953, scientists James Watson and Francis Crick made a groundbreaking discovery. Using Rosalind Franklin's X-ray images, they described the structure of DNA or Deoxyribonucleic acid.

DNA has a double-helical structure, resembling a spiral staircase.

The sides consist of sugar and phosphate molecules, while the steps consist of ni...
