Enzymes, with their enormous working capacity, result in perfect

replication of DNA. This phenomenon is constantly taking place at
great speed in every cell in the human body. Each and every day, in fact,
some 20,000 repair processes are carried out in every one of the human
body's 100 trillion cells. 71
The enzymes that work to replicate DNA operate as quickly as
permitted by the great care they take. In a striking way, enzymes work-
ing on DNA determine their speed according to the reactions they must
perform. For example, DNA polymerase completes only some 10 or so
bases a second. This rate is fairly slow, compared to enzymes such as
catalase, which breaks down 5 million hydrogen peroxide molecules a

second. This speed is determined by the quantity of copy DNA re-
quired by the body. The cell establishes its requirement, and the en-
zymes work in line with that production rate. At some places in the
body, enzymes literally have to work approaching the speed of light,
because where they operate, what counts is speed. The faster they com-
plete their reactions, the better the body will be able to remain healthy.
Production of the enzymes that work for DNA is another con-
trolled process. A large number of enzymes are involved in DNA repli-
cation, but their use and production are carried out economically.
Again, the DNA itself controls this. An on/off switch on the DNA (re-
pressor gene) keeps production under control. The switch is kept nor-
mally in an "off" position, until the need for an enzyme arises. 72

Even a small electron exchange taking place in the body is impor-
tant, and the results are very great. Every reaction must take place in a
controlled manner. Every reaction requires a division of labor, and the
involvement of countless enzymes all acting together. The duties and
speed of each one, and the molecules they will act upon, must all be
predetermined. Each enzyme must constantly strive to keep the cell
healthy and never make a mistake. So who makes all these determina-
tions? Who controls these and ensures that they are free of error? Who
