    Study Notes

    Frederick Sanger and the Sequencing of DNA

    • Frederick Sanger was a British biochemist who made significant contributions to molecular biology.
    • He was the first person to sequence a protein (insulin) and developed a method for sequencing DNA.
    • Sanger won two Nobel Prizes in Chemistry (1958 and 1980) for his work on the chemical structure of proteins and DNA.
    • He was awarded his first Nobel Prize for his determination of the amino acid sequence of insulin.
    • Sanger's method for DNA sequencing is known as the "Sanger method" or "dideoxy chain termination method."
    • He developed a method using radioactive isotopes to label individual fragments and build up the overlapping sequences.
    • Sanger’s method enabled scientists to map the first complete human genome in 1981.
    • Sanger is considered a pioneer in molecular biology, and his work has had a profound impact on our understanding of life.

    John Sulston

    • John Sulston is a British biologist who is known for his work on the Human Genome Project.
    • He was the first director of the Wellcome Sanger Institute, where he oversaw the sequencing of the Caenorhabditis elegans genome.
    • Sulston shared the 2002 Nobel Prize in Physiology or Medicine for his work on programmed cell death.
    • He played a key role in the Human Genome Project, which aimed to map all 3 billion base pairs of the human genome.
    • His research focused on C. elegans, a nematode worm with a fixed number of cells, making it ideal for studying cell differentiation and programmed cell death.
    • His breakthroughs helped to pave the way for understanding how genes control development and how they can go wrong in disease.
