Schotman: the cell cycle

In order for a cell to divide successfully, the cell must first

• duplicate its genetic information.

• decrease its volume.

• increase the number of chromosomes.

• decrease its number of organelles.

The process that increases genetic diversity within a population is

• asexual reproduction.

• sexual reproduction.

• cell division.

• binary fission.

Sister chromatids are attached to each other at an area called the

• centriole.

• centromere.

• spindle.

• d. chromosome.

If a cell has 20 chromosomes, how many chromosomes will each of its daughter cells have after cell division?

• 5

• 10

• 20

• 40

In plant cells, what forms midway between the divided nuclei during cytokinesis?

• nuclear membrane

• centromere

• cell membrane

• cell plate

During interphase a cell grows, duplicates organelles, and

• copies DNA.

• divides the nucleus.

• divides the cytoplasm.

• produces a new cell.

One difference between a cancer cell and a normal cell is that

• cancer cells divide uncontrollably.

• normal cells divide uncontrollably.

• cancer cells cannot make copies of DNA.

• normal cells cannot make copies of DNA.

Which statement about the process of binary fission is true?

• It does not involved the division of cytoplasm.

• It does not require any duplication of DNA.

• It does not take place in multicellular organisms.

• It does not produce genetically identical offspring.

What does a cell make during the synthesis stage of the cell cycle?

• more organelles

• a copy of DNA

• daughter cells

• greater surface area

The G1, G2, and S phases of the cell cycle make up

• telophase.

• cytokinesis.

• mitosis.

• interphase.
