BSCI-1510 Chapter : Chapter 11
Document Summary
Chapter eleven: prokaryotic cell division- occurs via binary fission. Bacteria have one circular chromosome: common aspects in all cell divisions: i. ii. Division of other cell parts in a similar manner: prokaryotes divide via binary fission i. Bacteria contain 1 circular chromosome (like the dna in mitochondria) rather than linear chromosomes (like eukaryotes) Bacteria can also contain plasmids (smaller, extra chromosomal circular. Dna molecules: binary fission process: ii. i. ii. iii. iv. Each daughter chromosome is than moved to 1 pole of the elongated cell. Plasma membrane grows inward to divide the cell in 2. New cell wall forms between 2 daughter cells, which each has 1 copy of chromosomal dna & a random number of plasmids v. Eukaryotic cell division: general points: definition of chromosome, sister chromatids and how they exist in different parts of the cell cycle, chromosome: a segment of dna, generally in a packed state with proteins i.
