Numerical modeling of inhomogeneous DNA replication kinetics (1408.5216v1)

Abstract: We present a calculation technique for modeling inhomogeneous DNA replication kinetics, where replication factors such as initiation rates or fork speeds can change with both position and time. We can use our model to simulate data sets obtained by molecular combing, a widely used experimental technique for probing replication. We can also infer information about the replication program by fitting our model to experimental data sets and also test the efficacy of planned experiments by fitting our model to simulated data sets. We consider asynchronous data sets and illustrate how a lack of synchrony affects replication profiles. In addition to combing data, our technique is well-adapted to microarray-based studies of replication.
