摘要: Cellular chromosomes are typically visible only during mitosis or meiosis. However, premature chromosome condensation (PCC) of the G1 nucleus has been observed naturally in pollen mother cells Triticum x Secale hybrids (Bleier 1930), an Avena hybrid (Holden and Mota 1956), Haemanthus endosperm (Ostergren Bajer 1961). Viruses that can induce cell fusion, such as myxoviruses, herpes viruses, adenoviruses, have also shown to pulverization (Nichols et al. 1967). Pulverized result from DNA replication. Similarly, G1, S, G2 be condensed by fusing interphase with mitotic (Johnson Rao 1970).
