Bovine Growth Hormone (DNA Strand)
1:1 scale 4" x 36" and 14" x 2" x 1"

This model was made for a courtroom presentation.  The double-helix sections were made with plastic and wood beads on twisted rods.  They were mounted on clear acrylic tubing, capped off on the ends, screwed, and tapped so that they could mount to each other in different configurations.  The circular pieces included magnetic removable sections to allow the attorneys to show the two alternate configurations of each piece.
