26
Q

Prophase

A

a. Chromatin shortens and thickens (rods are visible).
b. Microtubules connect centrosomes (polar fibers).
c. Microtubules connect to chromosomes (kinetochore
fibers).
d. Chromosomes begin to move towards the cell’s equator.
e. Nuclear membrane begins to dissolve.

27
Q

Chromatin shortens and thickens (rods are visible).

28
Q

(polar fibers).

A

Microtubules connect centrosomes

29
Q

(kinetochore
fibers).

A

Microtubules connect to chromosomes

30
Q

Chromosomes begin to move towards the cell’s equator.

31
Q

Nuclear membrane begins to dissolve.

32
Q

Metaphase

A

a. Chromosomes are aligned along the equator.
b. Kinetochore fibers attach to centromeres on
chromosomes.
c. Phase ends when centromeres split and chromatids
begin to form single chromosomes.

33
Q

Chromosomes are aligned along the equator.

34
Q

Kinetochore fibers attach to centromeres on
chromosomes.

35
Q

Phase ends when centromeres split and chromatids
begin to form single chromosomes.

36
Q

Anaphase

A

The main event is the separation of chromosomes to
opposite poles.

37
Q

The main event is the separation of chromosomes to
opposite poles.

38
Q

Telophase

A

Chromosomes are at opposite poles.
b. Nuclear membrane reforms.
c. Other structures; centrosomes, fibers disappear.
d. In animal cells, a cleavage furrow begins during late
anaphase - region where the cell will split.
e. In plants, a cell plate forms since the cell wall is rigid.
f. Cytokinesis occurs.
