Replication
When the DNA molecule has been unzipped by the enzyme, the
two sides are exposed.
A second enzyme then follows along each of the opened sides
and fits new nucleotides to the exposed bases.
As seen above at left, a T has been fitted against the A, and
a G is being fitted to the C.
As seen above at right, the enzyme fits an A to the T and is
fitting a C to the G.
