We report here an expansion of these efforts by incorporation of an amino substituted variant of tryptophan into the "cyan" GFP mutant, which turned it into a "gold" variant.
Another report, linking tRNA function to auxin, described identification of an auxin response mutant, which turned out to be affected in a member of the tRNA CGC Ala family (Perry et al., 2005).
Given this, and the fact that tap mutant has a mild phenotype, the authors examined the tej-tap double mutant flies, which turned out to be sterile.
Importantly, none of the cell lines overexpressing Ero1β mutants of Cys and/or Cys, which turned out to be hyperactive (see below), expressed more protein than the Ero1β-WT-expressing cell line.
In a genetic screen to identify new components in plastid signalling, Ruckle et al (2007) recovered four mutants with a subtle gun phenotype, all of which turned out to be cry1 mutant alleles.
They noticed that one of their mutant mice sprouted dark, cancerous growths, which turned out to be melanoma lesions.
He did some practical work: he was the first man to work out how to freeze worms without killing them, so that interesting mutants could be preserved for later study; and he made a preliminary estimate of the amount of DNA in a worm which turned out to be almost exactly right (it has about a thirtieth as much as a human being).
We can feel the same way about the Lost Generation Paris that Mr. Wilson's character stumbles into, and also about the early decades of the cold war as travestied in "X Men: First Class," which turns its heroic mutants into Forrest Gumps, startlingly present at some of the big moments in midcentury global history.
His quest to find his assumed forefather's coffin not that Sir Francis Drake's actual coffin has never been found led to the golden statue of El Dorado, which turns people into mutants.
In Surf II, Eddie stars as Menlo Schwartzer, a maniacal teenage scientist who creates a chemically-altered soft drink which turns its drinkers into mutant zombie punk rockers in a diabolical scheme to rid the beaches of surfers.
