Document Summary
Textbook reference: chapter 11 in biology how life works (2nd ed. ) Cell replicates dna, increases in size, divids into 2 daughter cells. Requires the coordination of many components in tim and space. Ftsz ia a protein that encodes to form a ring at site of constriction where the new cell wall forms between the 2 daughter cells. It is present in the genomes of diverse bacteria and archaeons and plays a role in prokaryotic cell division. Two important processes: karyokinesis: division of the nucleus, cytokinesis: division of cytoplasm via formation of cleavage furrow, successful cell division requires: Full complement of dna must distribute to 2 daughter cells from a single parent cell. Parents must be large enough to divide in 2 and still contribute cytoplasmic components to daughter cells. New copy may be identical or have mutations. Produces exact copies of parenetal chromosomes, exacr copies (eukaryotic cell divison)
