Cell Cycle, Mitosis, Meiosis Review

During which phase does DNA replication occur?

• G1

• S

• G2

• M

What occurs at G1?

• Chromatin condenses to form chromosomses

• Cleavage of cytoplasm and formation of cell plate

• Period of growth and development between mitotic divisions

• Nuclear membrane, nucleolus, and chromatin fade

The cell cycle has checkpoints built in to ensure that each cell has met certain criteria before being allowed to move to the next stage. Which statement correctly identifies what happens prior to the cell being allowed to enter the G2 stage of the cell cycle?

• The cell makes RNA

• The nucleus divides

• DNA replication occurs

• The chromosomes align

Gamete production is known as

• Meiosis

• Mitosis

• Endocytosis

• Exocytosis

Which of the following best describes meiosis?

• Cells divide only once during meiosis

• Meiosis does not occur in reproductive cells

• The cells produced at the end of meiosis are genetically identical to the parent cell

• The cells produced at the end of meiosis contain half the number of chromosomes as the parent cell

What part of the cell cycle results in daughter cells?

• Mitosis

• Prophase

• Cytokinesis

• G2 checkpoint

What is the purpose of mitosis?

• It guarantees that each daughter cell has half the amount of DNA of parent cells

• It ensures that new nuclei have an exact copy of DNA

• It ensures the reproduction of mitochondria and chloroplasts

• It prevents the occurrence of cancer cells

Which sequence list the stages of the cell cycle in order?

• Metaphase, Telophase, Interphase, Anaphase, Cytokinesis, Prophase

• Prophase, Telophase, Metaphase, Anaphase, Cytokinesis, Interphase

• Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis

• Cytokinesis, Interphase, Anaphase, Metaphase, Prophase, Telophase

Which stage of the cell cycle shows the formation of spindle fibers and chromatin condensing into chromosomes

• Metaphase

• Interphase

• Anaphase

• Prophase

During prophase, chromosomes become visible, the spindle forms, and the nucleolus and nuclear envelope disappear. In which cellular process does prophase occur?

• Mitosis

• DNA Replication

• Interphase

• Growth phase
