cell cycle and mitosis review

What are the main phases of the cell cycle?

• Interphase, Mitosis, and Cytokinesis.

• G1 phase, S phase, and G2 phase.

• Prophase, Metaphase, and Anaphase.

• Cell growth, DNA replication, and cell division.

What is the difference between mitosis and cytokinesis?

• Mitosis is the division of the cytoplasm, while cytokinesis is the division of the nucleus.

• Mitosis is the process of DNA replication, while cytokinesis is the division of the nucleus.

• Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm.

• Mitosis and cytokinesis are the same process.

During which stage of mitosis do spindle fibers form, chromosomes appear, and nuclear materials disappear?

• Metaphase

• Anaphase

• Prophase

• Telophase

What is the S phase of interphase?

• The phase where cells divide into two daughter cells.

• The phase where DNA is replicated.

• The phase where the cell prepares for mitosis.

• The phase where RNA is synthesized.

What is the role of spindle fibers during mitosis?

• To help separate the chromosomes during cell division.

• To replicate DNA before cell division.

• To provide energy for the cell during division.

• To form the nuclear envelope after division.

What happens during telophase?

• Chromosomes condense and become visible, nuclear envelopes break down, and the cell prepares to divide.

• Chromosomes de-condense, nuclear envelopes reform, and the cell prepares to divide.

• Chromosomes are replicated, and the cell undergoes cytokinesis.

• Nuclear envelopes dissolve, and chromosomes align at the cell's equator.

Is cytokinesis a phase of mitosis?

• True

• False

• It is a part of interphase

• It occurs only in plant cells

What is the G1 phase of interphase?

• The phase where DNA is replicated.

• The first gap phase where the cell grows and synthesizes proteins.

• The phase where the cell divides into two daughter cells.

• The phase where the cell prepares for mitosis.

During which stage of mitosis do the chromosomes line up along the equator of the cell?

• Anaphase

• Telophase

• Metaphase

• Prophase

What happens during anaphase?

• Sister chromatids are pulled apart to opposite poles of the cell.

• Chromosomes align at the cell's equator.

• Nuclear envelope begins to reform around the chromosomes.

• Chromatids are replicated in preparation for division.
