Quotes & Sayings About Macromolecules

Although separating mitochondria and microsomes might appear worlds apart from the determination of the molecular weight of macromolecules, certain concepts were common to the two operations and could be usefully transposed from the latter to the former. — Christian De Duve

Neo-Darwinian language and conceptual structure itself ensures scientific failure: Major questions posed by zoologists cannot be answered from inside the neo-Darwinian straitjacket. Such questions include, for example, 'How do new structures arise in evolution?' 'Why, given so much environmental change, is stasis so prevalent in evolution as seen in the fossil record?' 'How did one group of organisms or set of macromolecules evolve from another?' The importance of these questions is not at issue; it is just that neo-Darwinians, restricted by their resuppositions, cannot answer them. — Lynn Margulis

I had become monomaniacal about DNA only in 1951 when I had just turned 23 and as a postdoctoral fellow was temporarily in Naples attending a small May meeting on biologically important macromolecules. — James D. Watson

Give us detailed, testable, mechanistic accounts for the origin of life, the origin of the genetic code, the origin of ubiquitous bio macromolecules and assemblages like the ribosome, and the origin of molecular machines like the bacterial flagellum, and intelligent design will die a quick and painless death. — William A. Dembski

The structure of many cellular macromolecules has been revealed at the atomic level using x-ray crystallography. — Gunter Blobel

Twentieth-century developments in science support a new animism. Developments in physics have led to a world of energetic events which seem to be self-moving and to behave in unpredictable ways. And recent studies in biology seem to demonstrate that bacteria and macromolecules have elemental forms of perception, memory, choice, and self-motion. — David Ray Griffin

The macromolecules of organic life embody information in an intricate structure. A single hemoglobin molecule comprises four chains of polypeptides, two with 141 amino acids and two with 146, in strict linear sequence, bonded and folded together. Atoms of hydrogen, oxygen, carbon, and iron could mingle randomly for the lifetime of the universe and be no more likely to form hemoglobin than the proverbial chimpanzees to type the works of Shakespeare. Their genesis requires energy; they are built up from simpler, less patterned parts, and the law of entropy applies. For earthly life, the energy comes as photons from the sun. The information comes via evolution. — James Gleick

My three years at the NIH were critical in my scientific education. I learned an immense amount about the research process: developing assays, purifying macromolecules, documenting a discovery by many approaches, and writing clear manuscripts describing what is known and what remains to be investigated. — Stanley B. Prusiner
