摘要
生物遗传物质在细胞分裂过程中存在着复制、传递和变异,DNA的复制是细胞分裂的重要步骤和检查点,与核分裂之间存在着一种反馈,只有准确复制后,核分裂才能进行。在复制和传递过程中,存在着遗传物质的突变和重组。
During cell division, genetic material is existing the replication ,transfer and mutation. As an important process of cell division, a nucleus division has a feedback to DNA replication and always occurs after the nucleus division. There exist mutations and recombination during the process of hereditary material replication and transfer.
