What is it about the cyclic nature of nucleotides, both monomers and dimers, that makes them such favorites for signaling purposes?
It is becoming increasingly apparent that bacteria and archaea living in various oligotrophic environments tend to be quite a bit smaller than most grown in the laboratory. If this is true for the majority of prokaryotes, what do you make of it?
