Combination Quote by Francis Crick

If the polymer chain assumes a helicoidal conformation in the crystalline state, and if it does not contain asymmetric carbon atoms, it can be…

We are sometimes asked what the result would be if we put four +'s in one gene. To answer this my colleagues have recently…

— Francis Crick

It now seems very likely that many of the 64 triplets, possibly most of them, may code one amino acid or another, and that…

— Francis Crick

The meaning of this observation is unclear, but it raises the unfortunate possibility of ambiguous triplets; that is, triplets which may code more than…

— Francis Crick

The results suggest a helical structure which must be very closely packed containing probably 2, 3 or 4 coaxial nucleic acid chains per helical…

— Rosalind Franklin

“In describing a protein it is now common to distinguish the primary, secondary and tertiary structures. The primary structure is simply the order, or…

The strands of the DNA double helix are held together by hydrogen bonding interactions between the complementary base pairs. Heating DNA in solution easily…

— Richard J. Roberts

Unfortunately it makes the unambiguous determination of triplets by these methods much more difficult than would be the case if there were only one…

— Francis Crick

After some minor pieces of theoretical study that I worked on, a student in my statistical mechanics class brought to my attention a problem…

— Rudolph A. Marcus

Each form has its pluses and its minuses.

— Margaret Atwood

It has yet to be shown by direct biochemical methods, as opposed to the indirect genetic evidence mentioned earlier, that the code is indeed…

— Francis Crick

“The helix contains two intertwined strands of DNA. It is "right-handed"-twisting upward as if driven by a right-handed screw. Across the molecule, it measures…
