plasm. As a result of a number of complex operations, the SH2 communi-
cation module is activated, and a connection is established with the tyro-
sine kinase antenna, which stimulates the relay of this message within
the cell.
Until recently, no one had any idea of how the
messages carried by hormones reached the nucleus so
speedily and with such precision. How is it that no
error is made in the course of the transmission of the
message? Indeed, the slightest error made in the proc-
ess of the transmission of a message would cause, for
example, a faulty protein production in the cells and
the collapse of a marvelous physical system. The lat-
est research has shown the existence of communica-
tion modules in cells. The SH2 module is only one of
an estimated hundreds of different communication
modules.
Within the cells, these modules function as com-
munication stations. Thanks to the wonderful system A base station
that they have established, messages are carried from
