The Cell Cycle 0.0 / 5 ? BiologyDNA, genetics and evolutionASAQA Created by: AliceCreated on: 28-05-14 10:02 What are the three stages of the cell cycle? Interphase, nuclear division, cell division 1 of 16 How long does 1 cell cycle take? 24 hours 2 of 16 What percentage of this cycle is Interphase? 90% 3 of 16 What are the three stages of Interphase? G1 (Growth 1), S (Synthesis), G2 (Growth 2) 4 of 16 In general, what does not happen in Interphase? There is no division 5 of 16 What happens in G1? Organelle proteins produced 6 of 16 What happens in S? DNA replicated 7 of 16 What happens in G2? Energy stores increased, organelles grow and divide 8 of 16 What happens in nuclear division? Nucleus either divides into 2 or 4, depending on whether the process is in Mitosis or Meiosis 9 of 16 What is the formal name for Cell Division? Cytokinesis 10 of 16 What happens in cell division? Whole cell thus divides into 2 or 4 11 of 16 What is cancer? Growth disorder of cells 12 of 16 What is cancer caused by? Damage to genes which regulate mitosis and cell cycle, causing uncontrolled cell growth, making a tumour which constantly expands 13 of 16 Drugs treat cancer disrupt the cell cycle in two ways. What are they? Prevent DNA from replicating in Interphase. Stop metaphase stage where spindles form, can't pull apart to divide. 14 of 16 The treatment of cancer affects other cells such as... Stops hair producing cells from being produced. 15 of 16 In the cell cycle graph, it takes 12 hours and there are 5 points highlighted. Name A, B, C, D, and E. A - Mitosis, B - Meiosis, C - Meiosis 1, D - Meiosis 2, E - Fertilisation 16 of 16
