有丝分裂(mitosis and meiosis主要指体细胞的繁分子及相关的蛋白经过复制后平均分配到两个子细胞中;包含两个紧密相连的过程:核分裂和质分裂。即细胞分裂为二,各含有一个核。分裂过程包括四个时期:前期、中期、后期、末期。在分裂过程中经过染色体有规律的和准确的分裂,而且在分裂中有纺锤丝的出现,故称有丝分裂。
meiosis - cell divides but chromosomes are not duplicated.the product is two haploid cells with slightly different DNA (due to crossing over of chromosomes when they line up in metaphase)mitosis - cell divides into two identical daughter cells.if the mother cell is diploid,the two daughter cells...
