Document Summary
As long as eukaryotes require daughter cells to be genetic copies of the parental cell, mitosis does well to divide replicated dna equally and precisely. An elaborate master program of molecular checks and balances ensures an orderly and timely progession through the cell cycle. Through regulation of cell cycle, a process of dna synthesis replicates each dna chromosomes into 2 copies. Structural and mechanical web of interwoven cables and motors of the cytoskeleton separate replicated dna into precise daughter cells. @ a particular stage of cell cycle of sexually reproducing organisms, meiosis produces cells genetically different from parent cells. Meisois produces daughter nuclei different as daughter nuclei have the # of chromosomes parental nucleus had. Mechanisms involved in producing daughter nuclei produce arrangements of genes on chromosomes different from parent cell. Cells that are products of meisosis can function as gametes in animals and as spores in plants and fungi. 8. 3a chromosomes are the genetic units divided by mitosis.
