History
Zinc fingers were first identified in a study of transcription in the African clawed frog, Xenopus laevis. A study of the transcription of a particular RNA sequence revealed that the binding strength of a small transcription factor (transcription factor IIIA) was due to the presence of zinc-coordinating finger-like structures. The name "zinc finger" was proposed in the subsequent paper, in which a detailed study of this structure alone was conducted. More recent work in the characterization of proteins in various organisms has revealed the ubiquity of zinc ions in polypeptide stabilization.

Famous quotes containing the word history:
“A poet’s object is not to tell what actually happened but what could or would happen either probably or inevitably.... For this reason poetry is something more scientific and serious than history, because poetry tends to give general truths while history gives particular facts.”
—Aristotle (384–323 B.C.)
“What you don’t understand is that it is possible to be an atheist, it is possible not to know if God exists or why He should, and yet to believe that man does not live in a state of nature but in history, and that history as we know it now began with Christ, it was founded by Him on the Gospels.”
—Boris Pasternak (1890–1960)
“No event in American history is more misunderstood than the Vietnam War. It was misreported then, and it is misremembered now.”
—Richard M. Nixon (b. 1913)
