Q

Centromere

A

The duplicated strands of the DNA molecule can be seen to be attached long their length in this area

17
Q

Chromatid

A

Each DNA strand in the duplicated chromosome

18
Q

Centrioles

A

Tiny paired structures

19
Q

Metaphase

A

The second place of mitosis, is generally the shortest

20
Q

Anaphase

A

The third phase of mitosis

21
Q

Telophase

A

Following anaphase, the fourth and final phase of mitosis

22
Q

Cytokinesis

A

Completes the process of cell division, it splits one cell into two

23
Q

What two cells is Cytokinesis in?

A

Animal cells, plant cells

24
Q

What are some of the difficulties a cell faces as it increases in size?

A

The larger a cell becomes, the more demands the cell places on its DNA
