mitosis steps

Question 1

Interphase G1

Answer 1

Cell grows, performs normal functions

Question 2

Interphase S

Answer 2

DNA is replicated, sister chromatids remain joined at the centromere

Question 3

Interphase G2

Answer 3

Cell stockpiles molecules required to complete division process

Question 4

Prophase Stage 1

Answer 4

DNA in the form of chromatin begins to condense into visible chromosomes

Question 5

Prophase Stage 2

Answer 5

Nuclear membrane begins to disintegrate

Question 6

Prophase Stage 3

Answer 6

Spindle fibers begin to form, originating at the poles of the cell and joined to each sister chromatid

Question 7

Prophase Stage 4

Answer 7

DNA is fully condensed and spindle fibers are formed

Question 8

Metaphase

Answer 8

Chromosomes are pulled by the spindle fibers and aligned across the equator of the cell

Question 9

Anaphase

Answer 9

Sister chromatids are separated at the centromere and pulled to opposite poles of the cell by spindle fibers

Question 10

Telophase

Answer 10

Chromosomes are enclosed in a new nuclear membrane; spindle fibers break down, DNA in chromosomes returns to chromatin form

Question 11

Cytokinesis Stage 1

Answer 11

Cytoplasm divides cell in half

Question 12

Cytokinesis Stage 2

Answer 12

in plant cells, a cell plate forms dividing the the cell into two
in animal cells, a cleavage furrow forms and pinches the cell into two

Question 13

Cytokinesis Stage 3

Answer 13

Results in two genetically identical daughter cells
