binary fission -> division of single parent bacterial cell into 2 genetically identical daughter cells

DR;

circular dsDNA replicates, begins @ ori, results in formation of repn bubble >

DNA double helix separates into 2 strands, each strand template for synthesis of daughter strand by SCDR >

from single ori, DNA synthesis progresses in both directions around circular chromosome until entire chromosome replicated >

CS;

newly formed & original ori move to opp poles of cell >

cell elongates by producing > cytoplasmic, CSM & cell wall components to prep for division into 2

Ck;

once DNA replication complete, bact reach 2x initial size, CSM starts to invaginate >

CSM invagination & new peptidoglycan cell wall deposition divides parent cell into 2 GI daughter cells >

parent bact cell contains plasmids, may not be segregated equally into daughter cells
