✦ Synopsis

Fluctuating bond model of DNA gel electrophoresis

We present a Monte Carlo algorithm that allows a small length scale numerical study of DNA gel electrophoresis in high electric fields, similar to the fluctuating bond model for dynamical properties of polymeric systems. This approach combines advantages of lattice Monte Carlo methods with those from continuous Brownian dynamics algorithms, and also takes into account the persistence length of DNA, as well as the random nature of the gel.The initial orientation and acceleration of a random-walk DNA conformation shows a number of features that can be related to experimental results. The detailed description of DNA motion provided by this approach may lead to a first realistic computer study of the process of DNA sequencing.

The biased reptation model provides a good framework for interpreting the results of continuous field DNA electrophoresis experiments performed in agar-gels. Here we discuss the main features of the mobility-molecular size and mobility-gel concentration diagrams as obtained from new extensive comput

Plotting fragment length against reciprocal of mobility gives a straight line over a wider range than the conventional semilogarithmic plot. Curvature can be removed by a simple correction. A method is also given for determining molecular weights from mobilities by direct calculation.
