About Eduqas A Level Biology Cell Division
This topic compares mitosis and meiosis. Root tip squash is the linked practical.
What you need to know
- Cell cycle Interphase (G1, S, G2), mitosis and cytokinesis.
- Mitosis Prophase, metaphase, anaphase and telophase produce two genetically identical diploid cells for growth and repair.
- Meiosis Two divisions produce four haploid cells, with crossing over and independent assortment creating variation.
- Cancer Uncontrolled cell division when the cell cycle is not regulated.
Common mistakes in Cell Division
- Saying DNA replicates during prophase.
- Mixing up mitosis and meiosis outcomes.
- Confusing chromatids and chromosomes.
Try three Cell Division exam-style questions
1. State when DNA replication occurs in the cell cycle. (1 mark)
Show the mark scheme answer
During the S phase of interphase.
2. Give two differences between mitosis and meiosis. (2 marks)
Show the mark scheme answer
Any two: mitosis gives two cells, meiosis four; mitosis diploid, meiosis haploid; meiosis produces variation (1 each).
3. Explain how crossing over increases variation. (2 marks)
Show the mark scheme answer
Non-sister chromatids of homologous chromosomes exchange sections (1), producing new combinations of alleles (1).
