Mitosis & CELL CYCLE

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.

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?

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.
