Zinc Finger Nuclease DNA Cleavage (2D)

Zinc finger nucleases cut DNA only when two independently-searching halves come together at the right spacing. This 2D counterpart renders the DNA as a linear coordinate track and drives each ZFN monomer with a genuine one-dimensional facilitated-diffusion random walk — Brownian sliding along the strand punctuated by long-range hops — instead of a flattened camera view of a 3D helix. Once both monomers capture their flanking half-sites, the same Gaussian spacer-geometry match score gates whether the tethered FokI domains successfully dimerize and cleave, and a live parameter-space landscape panel plots that match score directly against spacer length alongside a running on-target/off-target cut tally, making the geometry dependence and the wild-type-vs-heterodimer off-target risk directly legible as data rather than as a rendered scene.
