Science vs. Evolution
"In bacteria, for example, Jacob and Monod demonstrated
a control system that operates by switching off
'repressor' molecules, i.e., unmasking DNA at the correct
'line number' to read off the correct (polypeptide)
subroutines. With eukaryotes [a common type of bacteria],
Britten and Davidson have tentatively suggested
that 'sensor genes' react to an incoming stimulus and
cause the production of RNA. This, in turn, activates a
'producer gene,' m-RNA is synthesized and the required
protein eventually assembled as a ribosome. Many DNA
base sequences may thus be involved, not in protein or
RNA production, but in control over that production—
in switching the right sequences on or off at the right
time."—*Michael Pitman, Adam and Evolution (1984),
p. 124.
