Figure 2From: Genome-wide estimation of firing efficiencies of origins of DNA replication from time-course copy number variation dataIllustration of the firing time and its relevance to firing efficiency. Replication forks/windows from N origins can arrive before replication completion time T100 of origin k. Origin k starts to fire at time t k . The firing efficiency is then determined from the relative amount of active replication by origin k and passive replications by other origins.Back to article page
