What advantages are produced in an athlete taking growth factors? • What are the health risks of taking anabolic steriods? • Why are these substances banned from sport? What are the ethical arguments?
What advantages are produced in an athlete taking growth factors? • Anabolic steroids are similar to the hormone testosterone. • The effects are similar to those seen in puberty changes .
What are the health risks of taking anabolic steroids? • Side effects include: • Liver damage failure • Facial hair growth (in ladies!) • Voice becomes deeper (in ladies!) • Impotence, shrinking testes, breast development (in gentlemen!) • Enlarged organs heart.
Why are these substances banned from sport? • What are the ethical arguments?
Genetic modificationOrganism Genetic modification Purpose • For your organism explain using an A4 poster the impact of the modification. • Answer the following questions which you will present to the audience: • What are the implications for human safety? • What are the implications for the environment? • What are the ethical issues?
Gene Therapy • Diseases with the capacity to be treated by gene therapy. • Cystic Fibrosis, Cancer & Haemophilia. • How can genes be introduced? • The use of viruses
Gene therapies of cancer • Markers on cancerous cells • Stop or die genes activated in cancer cells • Sensitisation to drugs &/or radiation • Introduction of genes which dominate genes with a predisposition • To eradicate faulty genes would require
Home work • http://gslc.genetics.utah.edu • Select: ‘Gene therapy: molecular bandage’ • ‘What is gene therapy?’ • ‘When a gene code is altered’ Write three sentences about what you learn Write three Qs which you cannot answer and need to research
B2 Topic 3 - Energy Flow • B2 3.1 recall that plant and animal cells are similar because they contain nuclei, cytoplasm and membranes and that plant cells also have cellulose cell walls, chloroplasts containing chlorophyll and vacuoles. • B2 3.2 recall the reactants (carbon dioxide, water) for and products (glucose, oxygen) of photosynthesis. • B2 3.3 explore human exploitation of plants, including their use as a food source.
