★ AQA Specification Reference: - 3.2.2 All cells arise from other cells. Eukaryotic cells that do retain the ability to divide show a cell cycle. DNA replication occurs during the interphase of the cell cycle. Mitosis is the part of the cell cycle in which a eukaryotic cell divides to produce two daughter cells, each with the identical copies of DNA produced by the parent cell during DNA replication. Division of the cytoplasm (cytokinesis) usually occurs, producing two new cells.

 

★ CIE Specification Reference: - 5. The mitotic cell cycle: When body cells reach a certain size they divide into two. Nuclear division occurs first, followed by division of the cytoplasm. The mitotic cell cycle of eukaryotes involves DNA replication followed by nuclear division. This ensures the genetic uniformity of all daughter cells. Candidates will be expected to use the knowledge gained in this section to solve problems in familiar and unfamiliar contexts. c) outline the cell cycle, including interphase (growth in G1 and G2 phases and DNA replication in S phase), mitosis and cytokinesis.

 

★ Edexcel (Biology A – Salters-Nuffield) Specification Reference: - Topic 3: Voice of the Genome. 3.10 Understand the role of mitosis and the cell cycle in producing identical daughter cells for growth.

 

★ Edexcel (Biology B) Specification Reference: - Topic 2: Cells, Viruses and Reproduction of Living Things. 2.3 Eukaryotic cell cycle and division. i Know that the cell cycle is a regulated process in which cells divide into two identical daughter cells, and that this process consists of three main stages: interphase, mitosis and cytokinesis. ii Understand what happens to genetic material during the cell cycle, including the stages of mitosis.

 

★ OCR (Biology A) Specification Reference: - Module 2: Foundations in biology. 2.1.6 Cell division, cell diversity and cellular organisation. Learners should be able to demonstrate and apply their knowledge and understanding of: the cell cycle - To include the processes taking place during interphase (G1, S and G2), mitosis and cytokinesis, leading to genetically identical cells.

 

★ OCR (Biology B) Specification Reference: - Module 3: Cell division, development and disease control Learners should be able to demonstrate and apply their knowledge and understanding of: the cell cycle - To include the processes taking place during interphase (G1, S and G2), mitosis and cytokinesis, leading to genetically identical cells.

 

★ WJEC Specification Reference: -2. Genetic information is copied and passed on to daughter cells. This topic covers cell division. During the cell cycle, genetic information is copied and passed on to daughter cells.
