second mitosis division. 2.Homologous chromosomes: Homologous chromosomes line up and then separate. In Meiosis 1‚ chromosomes in a diploid cell resegregate‚ producing four haploid daughter cells. It is this step in Meiosis that generates genetic diversity. 3.Sister Chromatid: Sister chromatids are generated when a single chromosome is replicated into two copies of itself‚ these copies being called sister chromatids. Compare sister chromatids to homologous chromosomes‚ which are the two different copies of

The Rise of the Superbugs A Superbug is a bacterium that can live in the human body and has the ability to withstand all forms of antibiotic medication. Superbugs are becoming increasingly significant in modern medicine as they are becoming more and more resistant to antibiotics. Antibiotics were discovered in 1928 by Alexander Fleming (Walsh and McManus‚ 2000). This resulted in a huge movement forward in medical history and even greatened human life expectancy. Since then antibiotics have been

Biology assignment - In Vitro Fertilization. In Vitro Fertilization (IVF)‚ is the procedure whereby human babies are conceived‚ not in the womb but in a test tube or a Petri dish. This procedure has become one of the greatest developments in the world of medical technology. In Vitro Fertilization has given infertile couples the chance to conceive and bear a child from a full term of pregnancy. Without this procedure‚ their infertility would render them childless. There are many aspects of
