binary fission Flashcards
1
Q
binary fission stages
A
DNA replication, attachment, cell elongation, Z-ring formation, constriction, septum formation, cytokenesis
2
Q
dna replication
A
replication begins at origin of replication
helicase, primase and DNA polymerase ||| come together to form replisome. replication then proceeds in both directions toward terminus
3
Q
attachment
A
chromosomes attaches to cell membrane
4
Q
cell elongation
A
cell grows in length as new cell wall material is laid down
5
Q
Z-ring formation
A
Z-ring forms in cell centre
6
Q
constriction
A
Z-Ring constricts and pulls in cell membrane and wall
7
Q
cytokinesis
A
cell wall degrading enzymes
digest the centre of the cell wall dividing septum resulting in two seperate cells
8
Q
septum formation
A
new cell wall forms along middle of cell
