Questions & Answers

Q: How did the speaker's interest in genetics develop, and what role did Linus Pauling play in their journey?

The speaker became interested in genetics after reading Schrodinger's book, which emphasized the importance of information on chromosomes. Linus Pauling, a renowned chemist, proposed a three-stranded structure of DNA that the speaker found to be incorrect through their own research.

Q: How did the speaker and Francis Crick come to discover the structure of DNA?

The speaker and Crick collaborated at the Cavendish Laboratory in Cambridge, where they used x-ray crystallography to study DNA. They built models based on previous work by Maurice Wilkins and Rosalind Franklin, eventually discovering the base pairing and the double helix structure of DNA.

Q: What is the significance of the speaker's research on autism and schizophrenia?

Using DNA analysis, the speaker's team has identified genetic variations that are associated with autism and schizophrenia. These findings provide insights into the underlying causes of these disorders and could potentially lead to improved diagnosis and treatment methods.

Q: How does the speaker's research on DNA analysis for cancer help in understanding and treating the disease?

By analyzing DNA variations in cancer cells, the speaker's team aims to develop DNA biopsies that provide a better understanding of the specific genetic changes driving individual cancers. This information can then be used to guide personalized treatment approaches and improve patient outcomes.
