Yes, there were definitely some compromises made in the LEGO DNA model.
The eight base-pairs/turn was the most obvious. Basically, I needed, in
a short timeframe, to come up with a fair representation of the 'idea of
a DNA molecule'... and I think that this model looks more like a DNA
structure than it does anything else [grin].

A while back a number of 'mathematically inclined' LEGO models were

Here's my contribution to such a theme:

Very nice, Eric!

As a biologist, I've been toying with the idea of building a DNA molecule
myself.  Here are some details you might like to know (or, maybe not?):

1) You have eight base-pairs per turn of the helix, an obvious and sensible
choice for Lego modeling.  The pitch of real DNA is sightly over ten bases per
turn.

2) The grooves between the bases are equally spaced in your model, and the base
pairs are represented as straight lines going straight through the central
axis.  In real DNA, there's a "major groove" and a "minor groove," and the
bases do not directly oppose each other.  They meet at an angle.  This also
complicates modeling.
