James D. Watson and Francis Crick determined the structure of DNA in 1953, using the X-ray crystallography work of Rosalind Franklin that indicated DNA had a helical structure (i.e., shaped like a corkscrew).
James Watson miwah Francis Crick nentuang struktur DNA ring warsa 1953, ngawigunayang kristalografi sinar-X pakaryan Rosalind Franklin miwah Maurice Wilkins sané nyihnayang DNA madué struktur heliks (inggih punika, mawentuk sekadi pangempugan botol).
