i) Bacteria reproduce asexually through binary fission.
ii) Binary fission takes place about every 20 minutes.
iii) Bacteria have a single circular chromosome made of DNA.
iv) When DNA molecule replicates, it results in the formation of two
chromosomes.
v) These two chromosomes move towards opposite sides.
vi) Middle portion of cell membrane invaginates inwards. When it meets at
centre it separates into two halves.
vii) New cell wall is deposited between two cross cell membranes.
viii) The daughter bacteria grow to their normal size, and then separate from
one another.
