Honors Cell Cycle Review

Which part of the cell cycle is this cell in?

• Interphase, because this is showing telophase

• Interphase, because this is showing S phase

• Mitotic phase, because this is showing telophase

• Mitotic phase, because this is showing anaphase

Select the best description for how we know the cell pictured is in Telophase.

• There are two sets of DNA but the cytoplasm hasn't divided.

• The chromosomes are pulled towards opposite ends of the cell.

• There are two complete daughter cells.

• There is a metaphase plate.

Select the correct progression of chromosomes through mitosis.

Which stage of mitosis is pictured?

• Telophase

• Anaphase

• Metaphase

• Prophase

The left cell is in interphase. Why are chromosomes not modeled in interphase?

• During interphase, the cell does not have genetic material.

• During interphase, the genetic material is uncondensed chromatin.

• During interphase, the DNA is unreplicated, so it is not visible.

• During interphase, the DNA is outside of the nucleus.

Different organisms have different number of chromosomes in their body cells. Select a true statement.

• A dog will have 78 chromosomes throughout interphase and mitotic phase.

• After mitosis, human cells have 23 chromosomes.

• A chimpanzee will have 24 chromosomes during S phase.

• A round worm will have 8 chromosomes during G2.

Something’s wrong with this picture! What might explain the unusual pattern seen in this cell?

• During metaphase, one of the chromosomes failed to attach to a spindle fiber.

• During telophase, the nuclei formed improperly.

• During prophase, the chromatin did not condense.

• The cell did not copy its DNA during anaphase.

What must this cell do BEFORE it can undergo mitosis? Select two answers.

• Replicate its DNA

• Cut its DNA in half

• Duplicate its centrosome

• Divide its cytoplasm

• Make spindle fibers
