Topic: Diseases and Bacteria Cells

B) 1: How can we fight bacteria? You can take antibacterial antibiotics. 2: How do scientists use bacteria to help us? Bacteria are the only living things which can fix nitrogen. Bacteria are the major decomposers of dead plants and animals. People use bacteria to turn wine into vinegar and milk into cheese and yogurt. 3: How do the disease cells mutate? DNA is constantly subject to mutations, accidental changes in its code. Few mutations are bad for you. In fact, some mutations can be beneficial. But the mutations we hear about most often are the ones that cause disease. Most inherited genetic diseases are recessive, which means that a person must inherit two copies of the mutated gene to inherit a disorder. This is one reason that marriage between close relatives is discouraged. Scientists estimate that every one of us has between 5 and 10 potentially deadly mutations in our genes-the good news is that because there's usually only one copy of the bad gene, these diseases don't manifest. 4: Do the different cells for different diseases look different when looked at under a microscope? Yes, very different. They have different body stuctures depending on the specific job it does. 5: Why do cells mutate? Cells mutate for many reasons. They mutate to survive in new climates. Some mutations happen during cell division, when DNA gets duplicated. Still other mutations are caused when DNA gets damaged by environmental factors, including UV radiation, chemicals, and viruses. 6: What can we do to prevent the cells from mutating? **Chlorophyllin protects genes.** Chlorophyllin refers to any one of a group of closely related water-soluble salts that are semi-synthetic derivatives of chlorophyll 7: What controls the division of disease cells? The nucleus. The nucleus acts as brain in a cell, therefor controls when and how the cells divide. 8: What do we use to create cures? Stem cells. 9: How to bacterial cells develop resistance? They prevent the antibioticsfrom reaching its designated point, or changing the target. 10: Why might a normal cell to become a diseased cell? Every cell in the body has a blueprint for diseased cells. Defects come once in a while and the cells develop using that blueprint. They are almost cells gone wrong.
