   DNA. A section of DNA contains a code for making a polypeptide and functional RNA. The code is a specific sequence of bases. Polypeptides make proteins, and genes determine the proteins of an organism. The location of a particular gene on a chromosome is called the locus.

   DNA is a working molecule; it must be replicated when a cell is ready to divide, and it must be “read” to produce the molecules, such as proteins, to carry out the functions of the cell. For this reason, the DNA is protected and packaged in very specific ways.

   How did Watson and Crick learn about DNA?

   • In Wilkins’ lab, researcher Rosalind Franklin was using X-ray crystallography to understand the structure of DNA. Watson and Crick were able to piece together the puzzle of the DNA molecule using Franklin's data (Figure 9.2). Watson and Crick also had key pieces of information available from other researchers such as Chargaff’s rules.

   What did Francis Crick and James Watson discover?

   • In the 1950s, Francis Crick and James Watson worked together at the University of Cambridge, England, to determine the structure of DNA. Other scientists, such as Linus Pauling and Maurice Wilkins, were also actively exploring this field. Pauling had discovered the secondary structure of proteins using X-ray crystallography.

   Who worked out the structure of DNA in the 1950s?

   • Scientists worked out the structure of DNA in the 1950s. Rosalind Franklin made ‘X-ray diffraction’ images of DNA. James Watson and Francis Crick used information from one of her images to work out a model for the structure of DNA. Work by Maurice Wilkins, a colleague of Franklin, supported their model.

   Who discovered the X-ray diffraction pattern of DNA?

   • In 1962, James Watson, Francis Crick, and Maurice Wilkins were awarded the Nobel Prize in Medicine for their work in determining the structure of DNA. Figure 9.2 Scientist Rosalind Franklin discovered the X-ray diffraction pattern of DNA, which helped to elucidate its double helix structure. (credit: modification of work by NIH)
