immediately identified and corrected. Incorrect DNA codes are
torn apart, replaced with correct ones, and then re-assembled. All these
processes take place at such a dizzying speed that a 3,000-step nucleotide is
produced in a minute, during which time all these steps are checked and
the necessary adjustments made many times (Figure 103).
As a result of external factors such as radiation or pollution, more er-
rors than normal may occur in the newly produced DNA molecule. This
time, the ribosomes in the cell begin to produce DNA-repairing enzymes in
light of the commands coming from the DNA. Thus the DNA is protected,
and the survival of the daughter cells—and the entire organism—is en-
sured (Figure 104).
Unknown to you, countless processes and supervision are performed,
and precautionary measures are taken, over the course of the day, to allow
you to continue with your life in a problem-free manner, with an astonish-
ing care and sense of responsibility. Each task is performed flawlessly and
successfully. Almighty God has placed countless atoms and molecules,
from the smallest (hydrogen atoms) to the largest (polymer molecules), at
