cell division - prokaryotic cells - binary fission

Question 1

1st step of binary fission ?

Answer 1

a bacterium has one circular chromosome that attatches to the inside of the plasma membrane
plasmid dna

Question 2

2nd step of binary fission ?

Answer 2

the cell duplicates its chromosome, attatches the copy beside the original, and adds membrane and wall materials between them
plasmids are also copied at this point if present
double the amount of dna

Question 3

3rd step of binary fission ?

Answer 3

when the cell has almost doubled in size, new membrane and wall are deposited across its midsection

Question 4

4th step of binary fission ?

Answer 4

the result of 2 genetically identical cells result

Question 5

compare the processes of binary fission and mitosis ?

Answer 5

similarities: both involve a prior stage where dna is replicated and cells grow in size
both undergo cytokenesis
both involve the production of 2 genetically identical daughter cells

differences: mitosis involves spindle fibres and binary fission does not
mitosis has definite stages such as pmat and binary fission does not
mitosis = eukaryotic cells
binary fission = prokaryotic cells
