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].
