Cell Cycle Quiz

What is the long period of the cell cycle between one mitosis and the next called?

• Interphase

• Prophase

• Metaphase

• Telophase

During which phase of Interphase are the cellular contents excluding the chromosomes duplicated?

• G1 phase

• S phase

• G2 phase

• M phase

What happens during the S phase of Interphase?

• Cellular contents excluding the chromosomes are duplicated

• Each of the 46 chromosomes is duplicated by the cell

• The cell "double checks" the duplicated chromosomes for error

• The chromosomes condense and become visible

What is the main event that occurs during Metaphase?

• The chromosomes line up in the middle of the cell

• The chromosomes condense and become visible

• The chromosomes decondense

• The cytoplasm divides

During which phase do the chromosomes decondense and the nuclear envelope form?

• Telophase

• Prophase

• Metaphase

• Anaphase

What is the area where sister chromatids are held together?

• Chromatid

• Centromere

• Spindle fibers

• Kinetochore

Which organelles are adjacent to the nucleus and consist of a cylinder with nine microtubules arranged peripherally in a circle?

• Centrioles

• Chromatids

• Spindle fibers

• Kinetochore

Which phase includes G1, S, and G2 phases?

• Cytokinesis

• Mitosis

• Interphase

• Anaphase

In which stage are each of the 46 chromosomes duplicated by the cell?

• G1

• G2

• S

• Mitosis

Which stage includes Prophase, Metaphase, Anaphase, and Telophase?

• Interphase

• Mitosis

• Cytokinesis

• G1
