Mitosis(有丝分裂)是体细胞的分裂方式,保持染色体数目不变,形成两个完全相同的子细胞,用于生物体生长发育。Meiosis(减数分裂)
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。
Mitosis involves a single cell division that results in two identical daughter cells, while meiosis consists of two successive divisions, producing four genetically distinct gametes.
meiosis and mitosis的意思 细胞分裂是生物体生长、发育和繁殖的基础过程,主要包括两种方式:梅里斯(meiosis)和米托斯(mitosis)。这两种细胞分裂方式在过程和意义上有很大的不同,但同时也存在一定的相似之处。 首先,我们来了解梅里斯(meiosis)。梅里斯是一种特殊的细胞分裂方式,主要发生在生殖细胞中,如精子和卵子。在...
