The DNA molecule is a coiled helix, consisting of two spirals, rath-
er like a staircase. The coils in the DNS spiral have an exceedingly reg-
ular structure. The vertebrae consisting of sugar and phosphate in both
DNA chains revolve at an equal distance around a common axis and
twist in the same direction, from right to left. Moreover, there is no hap-
hazard sequencing in the steps between the two arms. The bases that
make up the rungs form an angle of 90 degrees to the spiral axis, giv-
ing the DNA strip its highly regular, staircase-like appearance.
The steps are joined to one another with a special locking system.
The four different components of the rungs –adenine, guanine, cytosine
and thymine– are of different sizes. The adenine and guanine bases are
large, and cytosine and thymine are small molecules. The dimensions
of the molecules that will be opposite one another have been deter-
mined in such a way as to ensure equal spaces at every point on the spi-
ral staircase.
In order for the steps to be always regular, guanine always pairs
with cytosine, and adenine with thymine. Thus small bases always be-
ing opposite large ones in the DNA molecule means the distance is sta-
ble at every point. The result is a regular staircase extending with no in-
