   How did James Watson and Francis Crick make a model of DNA?

   • The images allowed precise calculations of the molecular spacing in DNA Building on Franklin’s work two scientists, James Watson and Francis Crick, made a model of the DNA structure approximately 2 years later. Their model was that of a double helix that consisted of evenly spaced pairs of bases connecting the two strands.

   Who invented DNA sequencing?

   • In 1977, Frederick Sanger, Allan Maxam, and Walter Gilbert developed methods to sequence DNA. This was supplemented in 1983 by Kary Mullis, who invented the polymerase chain reaction (PCR) to amplify DNA. Together these methods paved the way for sequencing of the human genome which began in 1990 and was completed 13 years later, in full.
