Original Abstract

The origin of replication (oriC) plays an important role in the cell cycle as the place where DNA replication is initiated. In bacterial cells, a single replication origin can be found and its correct identification is necessary in the annotation process of newly sequenced genomes. Although the rearrangement of a whole genome sequence according to oriC should be a standard procedure, public databases still contain lots of genomes starting at a random place. This situation complicates the comparative analysis of whole bacterial genomes as only two genomes rearranged according to oriC can be reliably aligned. In this paper, we present a novel technique for oriC prediction based exclusively on utilization of cumulated phase signal which distinguishes our approach from current techniques combining application of genomic signal processing techniques with a standard character based comparison. Proposed technique is therefore fast and suitably complements the current pipeline for comparison of whole bacterial genomes by aligned downsampled signals.
