Question

1. Match the stage of the cell cycle with the description of what is occurring inside the cell.

Interphase

Metaphase

Telophase

Prometaphase

Anaphase

Prophase

Cytokinesis

A. Chromosomes align in the center of the cell

B. The cytoplasm is divided into two new cells

C. Centrosomes form, cytoplasm doubles, and DNA doubles

D. The nuclear envelope breaks apart

E. nuclear envelope reforms, and the mitotic spindle disappears

F. Chromosomes become tightly coiled and the mitotic spindle begins to form

G. Sister chromatids are pulled apart and move towards the opposite ends of the cell

2. What is it called when two sister chromatids fail to properly separate during meiosis?

A. Nondisjunction

B. Crossing over

C. Recombination

D. Independent assortment

Interphase : C. Centrosomes form, cytoplasm doubles, and DNA doubles.

Metaphase :A. Chromosomes align in the center of the cell.

Telophase:E. nuclear envelope reforms, and the mitotic spindle disappears.

Prometaphase: F.Chromosomes become tightly coiled and the mitotic spindle begins to form.

Anaphase:G. Sister chromatids are pulled apart and move towards the opposite ends of the cell.

Prophase:D. The nuclear envelope breaks apart.

Cytokinesis :B. The cytoplasm is divided into two new cells.

2.The correct answer is: A.Nondisjunction

Reason:Nondisjunction best defines the above process and it causes aneuploidy.
