Cell Cycle and Mitosis

What does the replication of DNA during interphase ensure during cell replication?

• Crossing-over occurs prior to cell division.

• Mutations are corrected before the cell divides.

• Genetic variation is created in daughter cells.

• Each daughter cell gets an exact copy of the cell’s DNA.

The following diagrams are of a cell in the different phases of the cell cycle. Which is the correct order? (Make sure you increase the magnification of the picture.)

• 1 2 3 4 5 6

• 1 3 5 2 6

• 2 3 6 5 1 4

• 2 4 6 1 3 5

During which stage of interphase do chromosomes make a copy of themselves?

• Mitosis

• Growth 1

• Growth 2

• Synthesis

Before the process of mitosis can start, which must occur?

• DNA replication

When a cell divides by mitosis, what will be the genetic composition of the resulting two cells?

• They will be identical.

• There will be major differences.

• They will have minor differences.

• They will have one half the genes of the original.

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.
