Episode notes
Discovery of Thermus aquaticus
- Thermus aquaticus, a heat-loving bacterium, was discovered in Yellowstone by Hudson Freeze and Thomas Brock in the 1960s.
- This discovery expanded understanding of life's temperature limits and suggested life could thrive in extreme conditions.
Thermus aquaticus Enzyme Powers PCR
- The enzyme from Thermus aquaticus enabled PCR, a DNA 'Xerox machine' that revolutionized DNA reading.
- PCR drastically reduced the time and cost to study DNA, impacting genetics and biotechnology.
PCR Unlocks Human Genome
- PCR is considered a monumental scientific technique of the 20th century.
- It enabled the completion of the first human genome survey and widespread DNA research use.
