Understanding Mitosis and DNA Replication

What is the correct order of the stages of mitosis?

• Prophase, Metaphase, Anaphase, Telophase

• Metaphase, Prophase, Telophase, Anaphase

• Anaphase, Telophase, Prophase, Metaphase

• Telophase, Anaphase, Metaphase, Prophase

During which stage of mitosis do the chromosomes align at the cell's equatorial plane?

• Prophase

• Metaphase

• Anaphase

• Telophase

What is the primary purpose of DNA replication?

• To repair damaged DNA

• To produce RNA

• To ensure each daughter cell receives an identical set of chromosomes

• To synthesise proteins

Which enzyme is responsible for unwinding the DNA double helix during replication?

• DNA polymerase

• Helicase

• Ligase

• Primase

What is the role of DNA polymerase in DNA replication?

• Unwinding the DNA strand

• Joining Okazaki fragments

• Synthesising new DNA strands

• Adding RNA primers

Which structure holds the two sister chromatids together?

• Centromere

• Telomere

• Chromatin

• Nucleosome

What is the function of telomeres in chromosomes?

• To initiate DNA replication

• To protect the ends of chromosomes from deterioration

• To facilitate chromosome alignment during mitosis

• To bind sister chromatids together

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

• G1 phase

• S phase

• G2 phase

• M phase

What is cytokinesis?

• The division of the cell's nucleus

• The division of the cell's cytoplasm

• The replication of DNA

• The alignment of chromosomes

In animal cells, what structure is responsible for the physical separation of the cytoplasm during cytokinesis?

• Cell plate

• Cleavage furrow

• Spindle fibres

• Centriole
