Homologous vs replicated chromosomes
Did you know?
WebChromosome replication is a key function of living cells, and any factor that impedes progression of replication forks can result in mutagenesis and genome instability. Several pathways have evolved to rescue replication forks stalled by DNA damage, some of them involving homologous recombination between sister chromosomes.
