    Dear Tom,

    You may use the image, as long as you point out that the use of a left-handed DNA is intentional and not accidental.

    I am rather familiar with DNA structure, having worked on calculating circular dichroism spectra for DNA in A, B, and Z-conformation (Richterich P, Pohl FM, "Calculation of the CD of oligo (dG-dC): influence of basic optical parameters." Biopolymers. 1987 Feb;26(2):231-50).

    I did this work in the laboratory of Prof. Fritz Pohl, who in the 1960s set out to search from left-handed DNA, and discovered the B -> Z transitions of GC-oligomers when going from low salt to high salt (J Mol Biol. 1972 Jun 28;67(3):375-96; Proc Natl Acad Sci USA. 1986 Jul;83(14):4983-7).

    There are many who credit to Prof. Pohl the fact that the first crystal structure of DNA to be solved was left handed (see, for example, T J Thamann, R C Lord, A H Wang, and A Rich, "The high salt form of poly(dG-dC).poly(dG-dC) is left-handed Z-DNA: Raman spectra of crystals and solutions.", Nucleic Acids Res. 1981 October 24; 9 (20): 5443­5457). If I recall correctly, these crystallizations were actually carried out in low-salt and high-salt solutions; however, since the effective salt concentration in the crystals is very high, both solutions gave rise to left handed helices in the crystals.

    I chose a left-handed DNA for our logo in reverence to Prof. Pohl, an outstanding and very original scientist who I worked with during my undergraduate and graduate studies (and who unfortunately died at a young age). I am always interested in how many people notice that the helix in the picture is left-handed - very few people seem to notice it, so congratulations to Dennis Maeder for noticing.

    Best regards,

    Peter

  8. Nanomedicine, Volume I: Basic Capabilities by Robert A. Freitas Jr. shows that nanotechnology will be done using left handed DNA. This is very wise because left handed living things could always be identified and also they will form a separate ecosystem from normal right handed life forms. Just don't eat them! The ecological consequences, however, could be disasterous. binoculars First reported on 2004 March 1, new as of 2004 March 10 (Thanks to Dennis L.

    2004 March 19. Robert Freitas gave permission for the image, so long as this statement was made:
    Hello, Tom. Thanks to you and Dennis Maeder for noticing that the DNA pictured on the front cover of my book, Nanomedicine, Vol. I (1999) http://www.nanomedicine.com/NMI.htm, is intentionally left-handed rather than right-handed. Your implication that my book recommends employing left-handed DNA to build medical nanodevices, while amusing, is not quite right, since antibodies can recognize both B-DNA and Z-DNA. In fact, all of the nanorobotic devices I've proposed (e.g., respirocytes http://www.foresight.org/Nanomedicine/Respirocytes.html, microbivores http://www.rfreitas.com/Nano/Microbivores.htm, etc.) use mostly diamondoid materials in their construction, not DNA.

    My technical books make the case that in future years, it will be possible to construct medical nanorobots -- micron-sized mechanical robots built from molecularly-precise nanoscale components. A most important function of these nanorobots will be conducting in vivo cellular repair operations, including operations on individual macromolecules if necessary and even base-by-base repair or manufacture of DNA.

    The cover art for Volume I depicts tiny workers manually handling molecular components -- to emphasize that nanorobots will be capable of performing trajectory-constrained positional assembly, not just random-trajectory self-assembly as is customary in biology. The cover art also depicts the construction of Z-DNA rather than B-DNA -- to emphasize that nanorobots will not be restricted to manipulating conventional organic materials but can also build many useful "unnatural" molecular arrangements so long as those new arrangements are chemically stable. You'll also notice that my nanocaduceus logo image http://www.nanomedicine.com/Graphics/NanoMedRS.gif, featured prominently on the cover spine and inside my books and on my websites (and showing right-handed DNA!), depicts two similarly unnatural 7-fingered human hands -- to emphasize that the advent of nanorobotic medicine may allow us easily to modify our natural forms. Apparently these artistic subtleties have been lost on some readers.

    Best wishes,

    Just returned from the American Society for Microbiology annual meeting in New Orlea ns, where I encountered the exhibitor display pictured in the attached image. Gen-Probe makes various molecular genetic assays, primarily for the detection of infectious diseases.

    When I called attention to the fact that their DNA "scupture" (which rotates in real life) has the wrong handedness, the nice salepeople staffing the booth seemed less than concerned. They said that the error had been pointed out to them a couple of years ago, but no one else seemed to notice!

The goal of the Synthetic Biology Department is to design and construct novel organisms and biologically-inspired systems to help us solve problems that cannot be solved using natural systems." Apparently they are building left handed DNA organisms! This is a tough challenge because they will also have to build left handed DNA polymerases and ribosomes from scratch. Also, it will difficult to feed them, as Mr Tompkins discovered in a book by George Gamow when he got reversed. (Does anyone know the exact reference?

For your first visit to the Left Handed Hall of Fame page I suggest that you follow the story over all of the years. After that you can look at each year individually from the table below. Note: just because a year has gone by does not mean we haven't found more examples for that year!

1997 and 1998 were bumper crop years
and 1999 beat them more than 2 fold. 2000 was a record year, thanks to help from friends around the world (60 of the 97 cases, 63%!). 2001 exceeded even that record! 2002 was lower - are we making headway?
