rotein production in the cell is one of the miraculous phe-
nomena created by God. Every cell operates like a factory,
using the most advanced technology and organization. In
this micro-world, which is visible only under the most powerful micro-
scopes, extraordinary events take place.
Let us examine the main outlines of this protein factory that works
with the most flawless and perfect efficiency:
1. Whenever the body feels the need for any protein, a message ex-
pressing that need reaches the DNA molecule in the nuclei of the cells
where that production is to take place. Here, a very important point is to be
noted: Whenever there arises a need for any protein in the body, certain
messengers—themselves proteins!—can find all the relevant locations in
the body, know where they must go, and then transmit their message to the
right place in the proper form. The protein that establishes this communi-
cations finds its way in the total darkness of the bloodstream, without los-
ing its way, losing the message it carries or doing any harm to any part of it
(Figure 105).
