Question 2

area where replicated chromosomes (sister chromatids) attach.

Answer 2

centromere

Question 3

division of replicated DNA.

Answer 3

mitosis

Question 4

disc-shaped protein where
microtubules attach to centromere.

Answer 4

kinetechore

Question 5

__________ move objects within cell.

Answer 5

microtubules

Question 6

centrosome (centriole pair) with
growing microtubules.

Answer 6

Aster

Question 7

phase of mitosis where Chromatin condenses to chromosomes and Mitotic spindle begins to form.

Answer 7

Prophase

Question 8

phase of mitosis where Nuclear envelope breaks up and Microtubules attach to kinetochores
or to each other.

Answer 8

prometaphase

Question 9

phase of mitosis where Chromosomes line up.

Answer 9

metaphase

Question 10

phase of mitosis where Kinetochore microtubules shorten,
separating sister chromatids and Non-kinetochore microtubules elongate.

Answer 10

Anaphase

Question 11

_______ is when chromatids fail to
separate.

Answer 11

Nondisjunction

Question 12

phase of mitosis where Mitotic spindle breaks down. Nuclear envelopes reform. Chromatids relax into chromatin.

Answer 12

Telophase

Question 13

division of the cytoplasm following mitosis that forms two daughter cells.

Answer 13

cytokinesis
