Exploring the Stages of the Cell Cycle and Mitosis

What is the primary purpose of mitosis in eukaryotic cells?

• To increase the size of the cell

• To produce identical daughter cells

• To reduce the number of chromosomes

• To create different types of cells

What structure do chromosomes wrap around during condensation?

• Lipid bilayer

• Histone proteins

• Ribosomes

• Mitochondria

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

• G2 phase

• G1 phase

• S phase

• Mitosis

What is formed at the end of cytokinesis in plant cells?

• Cell plate

• Cleavage furrow

• Centrioles

• Spindle fibers

Which phase of mitosis involves the alignment of chromosomes at the cell equator?

• Metaphase

• Telophase

• Anaphase

• Prophase

What is the role of centrioles during mitosis?

• Chromosome condensation

• Protein synthesis

• Spindle formation

• DNA replication

Which checkpoint ensures that DNA has been replicated correctly before mitosis begins?

• Spindle checkpoint

• G2/M checkpoint

• Metaphase checkpoint

• G1/S checkpoint

What factors can influence the cell cycle and its progression?

• Growth factors and cell size

• Temperature and pressure

• Cell shape and volume

• Type of organelles present

Why do skin cells divide more frequently than neurons?

• Due to higher energy levels

• Because of constant wear and tear

• Skin cells are smaller

• Neurons have more DNA

What ensures the accuracy of mitosis?

• Rapid cell division

• Checkpoints during interphase

• Presence of multiple nuclei

• Absence of centrioles
