BI110 Lecture Notes - Lecture 7: Dna Replication, Cell Cycle, Mitosis
Document Summary
Prokaryotic cells undergo a cycle of binary fission involving coordinated cytoplasmic growth, dna replication, and cell division, producing two daughter cells from and original parent cell. The bacterial cell time in the cell cycle. Replication of the bacterial chromosome consumes most of the. Dna replication begins at a single sit called the origin replication (ori) through reactions catalyzed by enzymes located in the middle of the cell. Once the ori is duplicated, the two origins actively migrate to opposite ends of the cell. Division of the cytoplasm then occurs through a partition of cell wall material that grows inward until the cell is separated into two parts. Mitosis in eukaryotes is the basis for: growth and maintenance of body mass in multicellular. The reproduction of many single-celled eukaryotes eukaryotes: life cycle of a cell, which includes interphase (cell growth, Chromosomes of eukaryotic cells are individual, linear dna molecules with associated proteins.
