Dear Pierre,
let's think to a coli cell; it grows and then begins dividing; after a while,
we can see in the growth medium two cells (usually we say that they are
daughter cells, in respect to the preceding mother cell, but it is obvious that
this sentence is uncorrect; it's better to express ourselves in terms of
generations: a P cell and two F1 cells).
What do we find in F1 cells which was contained in the P cell (I think this is
a better expression, in respect to the term 'transmission', which implies that
the transmitter remains such during the transmission, while we have seen that
the P cell disappears)?
The answer is: everything. We find about half the P cell as the first F1 cell,
and the other half P cell as the second F1 cell. Substances, energy,
structures, functions, organization, (in)form(ation), processes, flows,
relations with the medium: anything is nearly exactly divided between the F1
cells.
Genetics focuses its attention on polynucleotides, but this is only a part of
the whole biological legacy.
