Abstract:
We present a computer model to predict the patterns expected for the replication intermediates (RIs) of DNA fragments analyzed by neutral/neutral two-dimensional (2D) agarose gel electrophoresis. The model relies on the mode of replication (uni- or bi-directional), the electrophoretic mobility of linear DNA fragments and the retardation caused by the three-dimensional shape of non-linear molecules. The utility of this model is demonstrated with two examples: replication analysis of the plasmids pBR322 and pHH5.8 in Escherichia coli after digestions with EcoRI and HindIII, respectively.
