Cyclic processes, morphologies

Eucaryotic cells execute their reproduction in a cyclic process, in which at least two phases, a S phase and a M phase, can be differentiated on the basis of biochemical and morphological features. The biochemical characteristic of the S (synthesis) phase is the replication of nuclear DNA and thus doubling of the genetic information. In M (mitosis) phase, division of the chromosomes between the daughter cells is prepared and carried out.

UV irradiation of poly(4-vinylbenzophenone) [poly(VBP)] in benzene solution, and in the presence of isopropanol as hydrogen donor, gives rise to a more complex picture [12,13]. Indeed, intra- and inter-molecular coupling reactions by the side-chain benzophenone ketyl radicals (K ) markedly change the macro-molecular morphology with the occurrence of cyclic and network structures as well as chain scission processes (Scheme 5).
