★ AQA Specification Reference: - 3.2 Cells: 3.2.2 All cells arise from other cells. 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. The behaviour of chromosomes during interphase, prophase, metaphase, anaphase and telophase of mitosis. The role of spindle fibres attached to centromeres in the separation of chromatids. Division of the cytoplasm (cytokinesis) usually occurs, producing two new cells.
★ CIE Specification Reference: - 5 The mitotic cell cycle. Explain the importance of mitosis in the production of genetically identical cells, growth, cell replacement, repair of tissues and asexual reproduction. 5.2 Chromosome behaviour in mitosis: describe, with the aid of photomicrographs and diagrams, the behaviour of chromosomes in plant and animal cells during the mitotic cell cycle and the associated behaviour of the nuclear envelope, cell surface membrane and the spindle (names of the main stages of mitosis are expected).
★ 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 and asexual reproduction.
★ 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. iii Understand how mitosis contributes to growth, repair and asexual reproduction.
★ OCR (Biology A) Specification Reference: - 2.1.6 Cell division, cell diversity and cellular organisation. The main stages of mitosis. To include the changes in the nuclear envelope, chromosomes, chromatids, centromere, centrioles, spindle fibres and cell membrane.
★ OCR (Biology B) Specification Reference: - 3.1.1 The developing cell: cell division and cell differentiation . The main stages of mitosis. To include the changes in the nuclear envelope, chromosomes, chromatids, centromere, centrioles, spindle fibres and cell membrane.
★ WJEC Specification Reference: - Continuity of Life. 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. (a) interphase and the main stages of mitosis (b) the significance of mitosis as a process in which daughter cells are provided with identical copies of genes and the process of cytokinesis.
