DNA Double Helix — 2D Twist, Base-Pairing & Replication Fork
A flat sine-wave rendering of the double-helix geometry: adjustable twist rate, base-pair count, rotation speed and a mutation slider drive the drawing, and a replication button animates a fork unzipping the helix and re-synthesizing each daughter strand.
This 2D companion draws the same helical math as the 3D model — 34° twist and 0.34 nm rise per base pair — as two out-of-phase sine curves instead of a rendered scene: colored rungs show real A-T and G-C pairing, a mutation slider flags mismatched rungs, and starting replication animates a fork unzipping the helix top to bottom while each strand grows a new complementary partner.
Sine-wave double helix with A-T/G-C base-pair rungs, adjustable twist rate and base-pair count, a mutation-rate slider, and an animated semi-conservative replication fork.
