Mitosis

Question 1

Karyotype

Answer 1

Visual representation of genome showing homologous pairs of autonomies (and x+y)

Question 2

Prophase

Answer 2

Chromosomes condense, nucleoli disappear, centrosomes move to opposite sides and mitotic spindles attach to sister chromatids and pul them to the Centre

Question 3

Metaphase

Answer 3

Duplicated chromosomes line up at the metaphase plate and kinetochore microtubules connect to the kinetochores of each sister chromatid

Question 4

Anaphase

Answer 4

Chromatids detach at the centromeres, kinetochore microtubules shorten and pull the chromatids to opposite sides of the cell. Non-kinetochore microtubules lengthen and the cell elongates

Question 5

Telophase

Answer 5

Chromosomes lengthen and nucleoli form in new nuclei. microtubules break down

Question 6

Cytokinesis

Answer 6

Animal cells have a cleavage furrow, plants have a cell plate that becomes a cell wall. Both separate the cell into two new ones

Question 7

Cell cycle

Answer 7

G1, S, G2, mitotic phase
