🎯 What you'll practice: The four phases of mitosis (PMAT) and their key events.
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1Chromatin condenses during:
2Chromosomes align at the metaphase plate during:
3Mitosis results in:
4Cytokinesis occurs alongside:
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5Sister chromatids separate during .
6Mitosis converts a 2n cell into 2n cells.
7List the four phases of mitosis in order.
8What happens to the nuclear envelope during prophase and telophase respectively?
9Name the three purposes of mitosis.
🚀 Section C · Challenge ● CHALLENGE 5
10Explain why mitosis produces genetically identical daughter cells, connecting this to DNA replication that occurs before mitosis begins.

1-A 2-B 3-B 4-D | 5 = anaphase 6 = 2 7 = prophase, metaphase, anaphase, telophase 8 = it breaks down in prophase and reforms in telophase 9 = growth, repair, asexual reproduction | 10 = Before mitosis begins, the cell's DNA is fully replicated during S phase of the cell cycle, producing two identical sister chromatids for every chromosome; because mitosis simply separates these already-identical sister chromatids into two new cells during anaphase, without any new genetic mixing, both daughter cells end up with an exact copy of the parent cell's genome.
