An alpha helix runs through eleven beta strands that make up this protein’s beta barrel structure. For 10 points each:
[10m] Name this protein, whose discovery won Osamu Smimomura, Martin Chalfie, and Roger Tsien the 2008 Nobel Prize in Chemistry. This protein is found in the A. victoria jellyfish.
ANSWER: GFP [or green fluorescent protein]
[10e] In 1992, Martin Chalfie expressed GFP in C. elegans, a model organism in this phylum of roundworms.
ANSWER: nematodes [or Nematoda]
[10h] Roger Tsien, along with his work in developing the red variant of GFP, developed microscopy techniques to image this element using fluorescence. This element’s ion is coordinated by 7 oxygen atoms in an EF-hand.
ANSWER: calcium [or Ca; accept Ca2+]
