tain in their DNA the genes needed to produce keratin and myosin,
ready for use at any time. But while skin cells use the genes for ker-
atin, the genes for myosin are skipped over. The enzyme that pro-
duces the mRNA finds and reads only the genes for keratin and takes
them to the ribosomes, the cell's production center. This way, the cell
produces no myosin or any other irrelevant protein, but only keratin.
It has finally become a skin cell and nothing else. In muscle cells, on
the other hand, the gene for myosin is "read" and the gene for keratin
skipped over.
As the embryo develops, the DNA must use each gene in a pro-
grammed manner as the need arises and ignore others. Hundreds of
proteins are needed for the formation of any particular type of cell. In
other words, while many genes are used or "read" in a particular cell,
many more genes coded for proteins for other specialized cells are
not. The DNA and all the genes must know when these genes need to
begin work, and when they need to stay out of action. If the DNA
lacked this control, and if other unwanted genes were read along with
ones the cell needed, this would result in a mass of tissue with cells of
different types all mixed together.
Consequently, with the magnificent plan and intelligence at
work here, we can see no created being who could possess such intel-
ligence. The truth is, the Master of this whole plan and extraordinary
system is God, the Lord of all the worlds; and there is no deity besides
Him.

Miraculous Journey

During embryonic growth, billions of cells need to settle in their
own special places, taking an amazing journey to where they belong.
This is called cell migration. Just as important as the location where the
cells are to wind up, is the timing of this event. During this develop-
ment in the womb, even a tiny mistake such as a cell moving to with-
in a hundredth of a millimeter of where it's supposed to go, or a
