8. 1 the cycle of cell growth and division: an overview. In mitotic cell division, dna replication is followed by the equal separation - that is, segregation - of the replicated dna molecules and their delivery to the daughter cells. The process ensures that the two cell products of a division have the same genetic information as the parent cell entering division. Mitosis is the basis for growth and maintenance of body mass in multi-celled eukaryotes and for the reproduction of many single celled eukaryotes. The chromosomes of eukaryotic cells are individual, linear dna molecules with associated proteins. Dna replication and the duplication of chromosomal proteins convert each chromosome into a structure composed of two exact copies known as sister chromatids. Prokaryotic cells undergo a cycle of binary ssion involving coordinated cytoplasmic growth, dna replication and cell division, producing two daughter cells from an original parent cell.
