Cell Cycle Basics

What is the longest phase of the cell cycle?

• Mitosis

• Cytokinesis

• Interphase

• Prophase

During which phase of the cell cycle does DNA replication occur?

• G1 phase

• M phase

• S phase

• G2 phase

What is the purpose of mitosis?

• To produce genetically diverse offspring

• To produce four daughter cells with half the number of chromosomes as the parent cell

• To produce two identical daughter cells with the same number of chromosomes as the parent cell.

• To repair damaged DNA in the cell

How many daughter cells are produced in mitosis?

• 3

• 5

• 4

• 2

What is the end result of meiosis?

• Four daughter cells with half the number of chromosomes

• Two daughter cells with the same number of chromosomes

• One daughter cell with double the number of chromosomes

• Three daughter cells with half the number of chromosomes

Which type of cell division results in genetically identical daughter cells?

• Binary fission

• Budding

• Meiosis

• Mitosis

What is the significance of cytokinesis in the cell cycle?

• Cytokinesis leads to the formation of new organelles in the cell

• Cytokinesis occurs before DNA replication in the cell cycle

• Cytokinesis is essential for the completion of the cell cycle and the generation of two genetically identical daughter cells.

• Cytokinesis is only relevant in prokaryotic cells

What are the stages of mitosis in order?

• prophase, metaphase, anaphase, telophase, prometaphase

• telophase, prophase, metaphase, anaphase, prometaphase

• prophase, prometaphase, metaphase, anaphase, telophase

• interphase, metaphase, telophase, anaphase, prophase

What is the difference between mitosis and meiosis?

• Mitosis produces genetically identical daughter cells, while meiosis produces genetically diverse daughter cells

• Mitosis occurs in somatic cells, while meiosis occurs in gametes

• The difference is in the timing of cell division

• The main difference between mitosis and meiosis is the number of daughter cells produced and the number of chromosomes in each daughter cell.

What is the role of centrioles in cell division?

• Regulate gene expression

• Organize spindle fibers for chromosome separation

• Help in cell membrane formation

• Store excess nutrients
