This lesson describes the key events that occur during interphase, mitosis and cytokinesis in the eukaryotic cell cycle. The PowerPoint and accompanying resources have been designed to cover point 5.1 [c] of the CIE A-level Biology specification and challenges the students on their knowledge of chromosomes from an earlier lesson as well as preparing them for upcoming lessons on the main stages of mitosis and its significance in life cycles
The students were introduced to the cell cycle at GCSE so this lesson has been planned to build on that knowledge and to emphasise that the M phase which includes mitosis (nuclear division) only occupies a small part of the cycle. The students will learn that interphase is the main stage and that this is split into three phases, G1, S and G2. A range of tasks which include exam-style questions, guided discussion points and quick quiz competitions are used to introduce key terms and values and to describe the main processes that occur in a very specific order. There is also a focus on the checkpoints, such as the restriction point that occurs before the S phase to ensure that the cell is ready for DNA replication. Extra time is taken to ensure that key terminology is included and understood, such as sister chromatid and centromere, and this focus helps to show how it is possible for genetically identical daughter cells to be formed at the end of the cycle. Important details of mitosis are introduced so students are ready for the next lesson, before the differences in cytokinesis in animal and plant cells are described.

Topics 5 & 6: The mitotic cell cycle, nucleic acids & protein synthesis (CIE A-level Biology)
This lesson bundle contains 11 detailed lesson PowerPoints, which along with their accompanying resources, have been intricately planned to cover the majority of the content of topics 5 and 6 of the CIE A-level Biology specification. The cell cycle, mitosis and protein synthesis are topics that students tend to find difficult and therefore the planning focused on the inclusion of a wide range of tasks that would not only promote the retention of important information and secure knowledge but also maintain motivation and engagement. The tasks include exam-style questions with displayed mark schemes which challenge the students on their current understanding and prior knowledge, guided discussion points and quick quiz competitions which introduce key terms and values. The following specification points are covered by these 11 lessons: Topic 5 * The structure of a chromosome, limited to DNA, histone proteins, chromatids, centromere and telomere * The importance of mitosis in producing genetically identical cells, growth, cell replacement, repair of tissues and asexual reproduction * The cell cycle, including theh G and S phases of interphase, mitosis and cytokinesis * The behaviour of chromosomes in animal and plant cells in the mitotic cell cycle Topic 6 * The structure of nucleotides, including ATP * The structure of DNA and RNA * The semi-conservative replication of DNA during interphase * A polypeptide is coded for by a gene * Gene mutations can cause changes to the polypeptide sequence * The information in DNA is used during transcription and translation to construct polypeptides

The cell cycle, mitosis and meiosis (CIE A-level Biology)
The three lessons included in this bundle describe the key events of the mitotic and meiotic cell cycles and cover the following points as detailed in topics 5 and 16 of the CIE A-level Biology specification: Topic 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 * Outline the cell cycle, including interphase, mitosis and cytokinesis * The behaviour of chromosomes in plant and animal cells during the mitotic cell cycle Topic 16: Inherited change * Explain what is meant by a pair of homologous chromosomes * The behaviour of chromosomes in plant and animal cells during meiosis * Explain how crossing over and random assortment of homologous chromosomes during meiosis and random fusion of gametes at fertilisation lead to genetic variation Each lesson is fully-resourced and the wide range of tasks found in the PowerPoint and the accompanying resources will check on current understanding and prior knowledge and engage the students with guided discussion points and quiz competitions.
