Everything about Kary Banks Mullis totally explained
Kary Banks Mullis, Ph.D. (born
December 28,
1944) is an American
biochemist and
Nobel laureate.
Dr Mullis was awarded the
Nobel Prize in Chemistry in 1993 for his development of the
Polymerase Chain Reaction (PCR), a central technique in
biochemistry and
molecular biology which allows the amplification of specified
DNA sequences. Dr Mullis subsequently was awarded the
Japan Prize that same year.
Early life and education
Mullis was born in
Lenoir, North Carolina, near the
Blue Ridge Mountains, on December 28, 1944. His family had a background in farming in the rural area, and as a child Mullis studied the diverse organisms of nearby farms. He grew up in
Columbia, South Carolina, He then proceeded to Xytronyx Inc. in 1986, where he was appointed the director of molecular biology, before moving on to serve as a nucleic acid chemistry consultant for multiple corporations.
In 1992, Mullis founded a business with the intent to sell pieces of jewelry containing the amplified DNA of famous people, such as musicians, to young people.
PCR and other inventions
In 1983, Mullis was working for Cetus. That spring, while driving his scooter and not watching the lines on the highway, Mullis conceived of the idea of using a pair of primers to bracket the desired sequence and copying it using DNA polymerase, but the polymerase was destroyed with each thermal cycle and had to be replaced. In 1986, he started to use
Thermophilus aquaticus (Taq)
DNA polymerase to amplify segments of DNA. The Taq polymerase was heat resistant and would only need to be added once, thus making the technique dramatically more affordable and subject to automation. This has created revolutions in
biochemistry,
molecular biology,
genetics,
medicine and
forensics.
Mullis has also invented a UV-sensitive
plastic that changes color in response to light, and most recently has been working on an approach for mobilizing the immune system to neutralize invading pathogens and toxins, leading to the formation of his current venture, Altermune LLC. This work is now being funded by
DARPA. Mullis described this idea this way:
It is a method using specific synthetic chemical linkers to divert an immune response from its nominal target to something completely different which you'd right now like to be temporarily immune to. Let's say you just got exposed to a new strain of the flu. You're already immune to alpha-1,3-galactosyl-galactose bonds. All humans are. Why not divert a fraction of those antibodies to the influenza strain you just picked up? A chemical linker synthesized with an alpha-1,3-gal-gal bond on one end and a DNA aptamer devised to bind specifically to the strain of influenza you've on the other end will link anti-alpha-Gal antibodies to the influenza virus and presto!--you have fooled your immune system into attacking the new virus. was Stuart Linn, who then used Kleppe's material in his own teachings to his students, including Mullis.
The suggestion that Mullis was solely responsible for the idea of using Taq polymerase in the PCR process has been refuted by his co-workers at the time. However, other scientists have said that "the full potential [ofPCR] wasn't realized" until Mullis' work in 1983, and at least one book has reported that Mullis' colleagues failed to see the potential of the technique when he presented it to them.
Controversies
HIV link to AIDS
Mullis has also drawn controversy for his past association with Peter Duesberg and his denialism about the evidence for the idea that HIV causes AIDS. As the recipient of a Nobel Prize for the PCR technique that's used to measure viral load in people with AIDS, he's often been cited by people within the AIDS denialist movement as someone who supports their views. Mullis wrote in an introduction to Duesberg's Inventing the Aids Virus (1997), "No one has ever proved that HIV causes AIDS. We have not been able to discover any good reasons why most of the people on earth believe that AIDS is a disease caused by a virus called HIV."
Mullis has said of HIV:
"If HIV has been here all along and it can be
passed from mother to child, wouldn't it make sense to test for the
antibodies in the mothers of anyone who is positive to HIV, especially if
that individual isn't showing any signs of disease?... If an HIV-positive woman develops
uterine cancer, for example, she's considered to have AIDS. If she's not
HIV-positive, she simply has uterine cancer. An HIV-positive man with
tuberculosis has AIDS; if he tests negative he simply has tuberculosis. If
he lives in Kenya or Colombia, where the test for HIV antibodies is too
expensive, he's simply presumed to have the antibodies and therefore AIDS,
and therefore he can be treated in the World Health Organization's clinic.
It's the only medical help available in some places."
Global warming
Mullis is skeptical about the concern over global warming, disagreeing with the theory that humans are a factor and also disagrees with the idea that CFCs cause ozone depletion.
OJ Simpson Trial
Dr. Mullis was supposed to be an expert witness, on the defendant's side, in the 1995 O. J. Simpson murder case. He witnessed most of the trial but wasn't called on during the trial.
Personal life
Mullis enjoys beach surfing.
Use of LSD
In a Q&A interview published in the September 1994 issue of
California Monthly, Mullis said, "Back in the 1960s and early '70s I took plenty of LSD. A lot of people were doing that in
Berkeley back then. And I found it to be a mind-opening experience. It was certainly much more important than any courses I ever took." During a symposium held for centenarian
Albert Hofmann, Hofmann revealed that he was told by Nobel-prize-winning chemist Kary Mullis that LSD had helped him develop the
polymerase chain reaction that helps amplify specific DNA sequences.
Books authored
- The Polymerase Chain Reaction, 1994, with Richard A. Gibbs
- Dancing Naked in the Mind Field. 1998, Vintage Books.
Mullis wrote the 1998
autobiography Dancing Naked in the Mind Field, which gives an account of his initial invention of PCR, as well as providing insights into the opinions and experiences of the author. Several examples of supposedly atypical behavior for a scientist, including the use of
LSD, belief in
astrology, and the belief in an
extraterrestrial encounter, are also chronicled within the book.
