There was a hound dog laying in the yard and an old geezer in overalls was sitting on the porch.
"Excuse me, sir, but does your dog bite?" the tourist asked.
The old man looked up over his newspaper and replied, "Nope."
As soon as the tourist stepped out of his car, the dog began snarling and growling, and then attacked both his arms and legs. As the tourist flailed around in the dust, he yelled, "I thought you said your dog didn't bite!"
The old man muttered, "Ain't my dog."
Sir Aaron KlugBorn 11 Aug 1926. British biochemist who received the 1982 Nobel Prize for Chemistry "for his development of crystallographic electron microscopy and his structural elucidation of biologically important nucleic acid-protein complexes." Whereas X-ray diffraction patterns reveal any highly ordered three-dimensional crystalline structures, the technique fails for those biological samples with less suitably ordered molecular structures. However Klug developed crystallographic electron microscopy which combined certain principles of the diffraction methods with electron miscroscopy so that he could figure out the 3-D structure of viruses or samples of complicated combinations of nucleic acids and proteins as found in membranes, muscle fibres and chromosomes.« |
