A hypothesis is presented concerning the configuration of DNA molecules in
a cell nucleus. It is shown that this configuration leads to cell division
and that the replication of DNA follows the Fibonacci numerical series. The
fertilisation of an ovum cell by a sperm cell is discussed on the basis of
the hypothesis along with considerations of the cloning of mammals. Also d
iscussed is the initiation of rapid division of cells associated with the f
ormation of cancerous conditions in cells. (C) 2001 Harcourt Publishers Ltd
