of catalytic proteins, or enzymes. In short, proteins cannot form without
DNA, but neither can DNA form without proteins. 194
According to the molecular biologist Michael Denton: "At the
heart of the problem lay a seeming paradox-proteins can do many
things, but they cannot perform the function of storing and transmit-
ting information for their own construction. On the other hand, DNA
can store information, but cannot manufacture anything nor duplicate
itself. So DNA needs proteins and proteins need DNA. A seemingly un-
breakable cycle-the ultimate chicken-and-egg prob-

lem." Andrew Scott describes the way that proteins
and the genetic code cannot be considered separate-
ly in an article in New Scientist magazine:
We are grappling here with a classic "chicken and egg" di-
lemma. Nucleic acids are required to make proteins,
whereas proteins are needed to make nucleic acids and
also to allow them to direct the process of protein man-
ufacture itself . . . The emergence of the gene-protein
link, an absolutely vital stage on the way up from life-
less atoms to ourselves, is still shrouded in almost com-
plete mystery. 196
This situation once again refutes the scenario
of life emerging by chance. The American chemist
Prof. Homer Jacobson has this to say:
Directions for the reproduction of plans, for energy and
the extraction of parts from the current environment, for
The diagram shows the protein known as the leucine zipper.
These structures, also known as main zipper proteins, are ex-
tremely important for normal development and play a regula-
tory role in DNA copying. Cancer may arise in the event they
are subjected to mutation.
