# Why a Particle Physicist is Interested in DNA Branch Migration

## TL;DR

This paper presents a discrete model of DNA branch migration that aligns with experimental data and explores its continuum approximation, offering insights for future research in molecular biology.

## Contribution

It introduces a new discrete model for DNA branch migration and compares it with continuum diffusion, aiding experimental design.

## Key findings

- Discrete model matches existing data
- Long strand migration well approximated by diffusion
- Model useful for guiding future experiments

## Abstract

We describe an explicitly discrete model of the process of DNA branch migration. The model matches the existing data well, but we find that branch migration along long strands of DNA ($N \simge 40$~bp) is also well modeled by continuum diffusion. The discrete model is still useful for guiding future experiments.
