right angle. If this weren't so and all amino acid bonds were of equal
strength, the protein formed would be straight, without function-in
fact, useless.
In short, a protein's three-dimensional shape is highly important.
Only because of their 3-D shape can enzymes in particular direct, reg-
ulate, and accelerate many reactions. Even if the protein possessed the
right number of amino acids in the correct order, its lack of correct geo-
metric shape would render it useless. In order to facilitate folding, the
bonds of attraction between amino acids need to be individually reg-
ulated with incredible control and sensitivity. Even the slightest detail
must be determined with care (see Figure 5.2).
Since the formation of even one protein molecule requires so
many processes and controls, today's technology has not been able to
synthesize a protein molecule under laboratory conditions. Yet evolu-
tionists, with their usual insensitivity and blindness, claim that such a
molecule came about in the primitive atmosphere as a result of coinci-
dences.
Let us look at the likelihood of a protein forming by chance, and
then contrast this impossibility with the hopeless position of the evo-
lutionists.
