Now you can demonstrate your love of biology and sock knitting at the same time!

These socks feature a DNA double-helix twisting down each side of the leg, then denaturing at the ankle so that one DNA strand travels down the heel flap and the other travels down the side of the foot. The minor and major grooves in the double-helix (the distance between the two strands in the helix, and between turns in the helix) are appropriately proportioned, and there are a nearly-accurate 10 bases per full turn of the helix.

The socks are knit top-down with a somewhat tricky heel flap (requiring cabling on right- and wrong-side rows, and following different chart rows on the two sides of the flap) but otherwise standard construction.

Erratum: 3/28/11 In the schematic, the Double Helix for Band B should start with Row 16 instead of Row 17. Thanks to VagusVenus for finding this mistake!
