Question

fred wants to summarize mitosis in the cell cycle. which statement describes mitosis? mitosis includes several steps that occur after the cytoplasm is divided but before the dna has been copied. mitosis includes several steps that occur after the dna has been copied but before the cytoplasm is divided. mitosis is the step in which the cytoplasm is divided. mitosis is the step in which the dna is copied.

Explanation:

Mitosis is a part of the cell cycle where the nucleus divides. After DNA replication (in the S - phase of interphase), mitosis occurs. Cytokinesis (cytoplasm division) happens after mitosis.

• Option 1: Mitosis occurs before cytoplasm division, so this is wrong.
• Option 2: DNA is copied before mitosis (in interphase), so this is wrong.
• Option 3: Mitosis is the nuclear division steps after DNA replication (in interphase) and before cytoplasm division (cytokinesis), this is correct.
• Option 4: DNA is copied in interphase (S - phase), not in mitosis.

Answer:

Mitosis includes several steps that occur after the DNA has been copied but before the cytoplasm is divided.
