单词	replicon
释义	replicon /ˈrɛplɪkɒn / noun Biology A nucleic acid molecule, or part of one, which replicates as a unit, beginning at a specific site within it.Nuclei have numerous replicons origins per chromosome, which can be replicated simultaneously - so replication time is mechanistically independent of genome size and can be far less than in bacteria.... This defective recovery of DNA replication suggests an inability to coordinate lesion bypass or to initiate new replicons. An important category of small replicons are the prophages, phages and other virus types. Origin 1960s: from replication + -on.
