Document Summary
Growth: increase in the number of cells. Binary fission: cell division following enlargement of a cell to twice its minimum size: how most prokaryotes divide once cell gives rise to two daughter cells. Generation time: time required for microbial cells to double in number can be as short as 15 minutes. During cell division each daughter cell receives a chromosome and sufficient copies of all other cell constituents exist as an independent cell. Location of ftsz ring is facilitated by min proteins used by e. coli to properly identify the septum prior to cell division. Prokaryotes contain a cell cytoskeleton that is dynamic and multifaceted. Mreb: major shape determining factor in prokaryotes that make them rod shaped: rod shaped without this protein it would form a sphere spherical cell do not have this protein. Crescentin: shape determining protein produced by vibrio-shaped cells of caulobacter crescentus.
