QUIZ #5

During which stage of mitosis do chromosomes align at the cell’s equator?

• Prophase

• Anaphase

• Metaphase

• Telophase

In prophase, chromosomes become:

• Invisible

• Less condensed

• Fully duplicated

• Visible and condensed

What key event occurs during anaphase of mitosis?

• Chromosomes pair up

• Nuclear envelope reforms

• Sister chromatids are pulled apart

• DNA replication

During telophase, which of the following occurs?

• Chromosomes condense

• Spindle fibers attach

• Nuclear envelope reforms

• Chromosomes line up

Which phase precedes mitosis and involves DNA replication?

• Prophase

• Interphase (S phase)

• Metaphase

• Cytokinesis

Cytokinesis results in:

• Separation of chromosomes

• Replication of DNA

• Division of the cytoplasm

• Disappearance of spindle fibers

Mitosis results in:

• 2 genetically identical diploid cells

• 2 genetically different haploid cells

• 4 genetically identical haploid cells

• 2 identical gametes

Which stage of meiosis I involves crossing over?

• Metaphase I

• Anaphase I

• Telophase I

• Prophase I

The homologous chromosomes separate during:

• Metaphase II

• Anaphase I

• Anaphase II

• Prophase I

Which of the following is true of meiosis II?

• DNA replication occurs again

• It separates sister chromatids

• It forms diploid cells

• Crossing over occurs
