Target Molecule

Famous quotes containing the words target and/or molecule:

“But this we know, the obstacle that checked
And tripped the body, shot the spirit on
Further than target ever showed or shone.”
—Robert Frost (1874–1963)

“We can come up with a working definition of life, which is what we did for the Viking mission to Mars. We said we could think in terms of a large molecule made up of carbon compounds that can replicate, or make copies of itself, and metabolize food and energy. So that’s the thought: macrocolecule, metabolism, replication.”
—Cyril Ponnamperuma (b. 1923)
