Meiosis - Cell Division

Question 1

Prophase 2

Answer 1

In cell A (and the same applies to cell B)
Each chromosome is visible as two chromatids
Centrosome splits into centrioles which moves to opposite poles
Nuclear membrane begins to disappear

Question 2

Metaphase 2

Answer 2

The chromosomes become arranged along the equator singly
Attached to the spindle threads

Question 3

Anaphase 2

Answer 3

The chromosomes split and the two chromatids making up each chromosome
Are pulled towards opposite poles
when the spindle threads contract

Each chromatid is really a single-stranded chromosome sine DNA replication took place in Interphase

Question 4

Telophase

Answer 4

Two groups of chromosomes occur-one at each end of the cell forming two new nuclei
The cytoplasm of cell A divides to form two new cells
In the same way cell B also divides to form two new cells
In total there are now four new cells
The nucleus in each of these four cells has half the number of chromosomes we originally started with in the first division
The four cells are generally different because of crossing over
