Steps of mitosis

Question 1

List all the steps of mitosis in order

Answer 1

Interphase
Prophase
Metaphase
Anaphase
Telophase

Question 2

What happens in interphase for mitosis?

Answer 2

-cells don’t divide
-all regular metabolic activities occurring
-chromosomes aren’t visible( they exist chromatin)
-chromosomes replication during S phase of interphase, results in sister chromatids attached at the centromere

Question 3

What happens in Prophase for mitosis?

Answer 3

• chromosomes become visible because they shorten and thicken

• in animal cells, centrioles move to opposite ends of the cell and provide attachment for SPINDLE FIBRES

• nuclear membrane begins to disappear

Question 4

What happens in Metaphase for mitosis?

Answer 4

•Spindle fibres are attached to centromeres
centromeres move sister chromatids to middle of cell

Question 5

What happens in Anaphase for mitosis?

Answer 5

•Centromeres divide and the daughter chromosomes move to the opposite side of the cell

Question 6

What happens in Telophase for mitosis?

Answer 6

•Chromosomes lengthen, spindle fibres dissolve and nuclear membrane forms around each set of chromatin

•followed by cytokinesis (division of cytoplasm)

Question 7

What is the process called after mitosis occurs and explain the processes?

Answer 7

-CYTOKINESIS
•in animal cells cleavage furrow devolops pinching cell into two
•in plant cells, cell plate forms into a new cell wall
