Question 1

Interphase is the shortest or longest stage and it is the what stage

Answer 1

Longest stage the prep stage

Question 2

Why is mitosis short ?

Answer 2

The phase is vulnerable because there is no nuclear membrane to protect and separation of chromosomes

Question 3

What are the stages of interphase ?

Answer 3

G1, S ,G2

Question 4

What happens during g1

Answer 4

Cellar contents excluding chromosomes are duplicated

Question 5

What happens during s

Answer 5

Each of the 46 chromosomes is duplicated by the cell

Question 6

What happens during G2

Answer 6

Cell double checks the duplicated chromosomes for error making repairs

Question 7

Prophase

Answer 7

Chromosomes condense become visible
Spindle divers emerge from centrosomes nuclear envelope breaks down
Centrosomes move toward opposite poles

Question 8

Metaphase

Answer 8

chromosomes lined up at metaphase plate
Each sister chromatid is attached to a spider fiber from opposite poles

Question 9

Anaphase

Answer 9

Centromeres split in two
Sister chromatids )now-called chromosomes ) are pulled toward opposite poles
Certain spindle fibers elongate cell

Question 10

Telophase

Answer 10

Chromosomes arrive at opposite poles and begin to decondense

Nuclear envelope material surrounds each set of chromatids

Mitotic spindle breaks down

Spindle fibers continue to push poles apart
