Sucrose gradient analysis: computer simulation and measurement of the parameters involved in the sedimentation of DNA molecules

M F Macchiato et al. Z Naturforsch C Biosci. 1977 Jul-Aug.

Abstract

The Montecarlo method is used to computer simulate a random distribution of molecular lengths generated by inducing T4 DNA fragmentation through the decay of 32P atoms introduced in the molecule. Taking into account the experimental conditions we find that the value of alpha for alkali sucrose gradients is 0.46 +/- 0.02 and does not depend on the running time. Our findings also prove that the computer simulation can be utilized to analyze sedimentation profiles of DNA molecules fragmented in vivo.
