Mitosis Inhibition Affects Cell Division-Dependent Processes

Steps:

• Mitosis divides cells to produce replacements for worn-out ones and support tissue repair.
• Uncontrolled mitosis drives tumour formation by rapid cell proliferation.
• Stem cell numbers remain stable as mitosis halt prevents division but not existing cell loss.
• Cell replacement (item 2) and tissue repair (4) require new cells, while tumours (5) depend on mitotic activity.

Why D is correct:

• Mitosis, the final stage of the cell cycle, generates daughter cells essential for replacement, repair, and tumour growth per standard cell biology definitions.

Why the others are wrong:

• A omits tissue repair, which needs mitotic cell production.
• B includes stem cell number, unaffected directly by mitosis stoppage.
• C duplicates D but lists incorrectly; D specifies 2, 4, 5 precisely.

Final answer: D
