Cell Cycle & Mitosis II

What role does the centromere play in cellular reproduction?

• It is the area where microtubules are formed.

• It is the area where the nucleus is during cell division.

• It is the area of alignment for the chromosomes.

• It is the area of attachment for chromatids.

Which factor BEST explains how many diseases, such as cancer, are formed within the body?

• A traumatic injury to the body has occurred.

• A disruption in the cell cycle has taken place.

• An allergic response was triggered.

• A mutation occurred during the process of crossing over.

Cell division is necessary for an organism to

• obtain nutrients.

• grow and reproduce.

• make proteins.

• conserve matter and energy.

The cell cycle describes the processes that take place as a cell

• absorbs nutrients.

• makes proteins.

• repairs old cells.

• forms new cells.

Which is the result of mitosis?

• two identical nuclei

• four unique cells

• a decrease in genes

• a new protein

During which phase of the cell cycle is the cell growing and preparing for cellular division?

• cytokinesis

• anaphase

• prophase

• interphase

What is the result when a single cell reproduces by mitosis?

• two cells with genetic material identical to the parent cell

• two cells with half the genetic material of the parent cell

• four cells with half the genetic material of the parent cell

• four cells with genetic material identical to parent cell

Before mitosis begins, which happens before the nucleus starts dividing?

• The cytoplasm separates.

• The DNA replicates.

• The sister chromatids separate.

• The homologous chromosomes cross over.

In which phase of the cell cycle is DNA replicated?

• gap1

• gap 2

• mitosis

• synthesis

What process involves the division of the cytoplasm?

• anaphase

• cytokinesis

• interphase

• prophase
