   How did we discover human DNA variability?

   • Back in 1977, the only tools we had available for exploring human DNA variability were probes which enabled us to detect, by nucleic acid hybridisation, specific regions of DNA in human chromosomes, and restriction enzymes that allowed us to cut DNA at predetermined sites.

   How did DNA testing start?

   • The roots of DNA testing can be traced back to the discovery of DNA itself in 1953 by James Watson and Francis Crick. Their groundbreaking work unveiled the double-helix structure of DNA, providing scientists with a fundamental understanding of how genetic information is stored and transmitted within living organisms.

   How has DNA testing influenced today's DNA collection methods?

   • The history of DNA testing has greatly influenced today’s dna collection methods. In the past, blood samples were the primary source of DNA. However, advancements have led to the use of swabs for a less invasive and more convenient approach to dna collection methods: swab vs blood samples.

   Who gave Maurice Wilkins DNA samples?

   • The above image shows the original samples of DNA which were given to Maurice Wilkins by Swiss biochemist Rudolf Signer. PhD student Raymond Gosling then used the samples to produce the first crystals of DNA and, with Rosalind Franklin, used them for the next generation of X-ray images.
