  • Three Of The Many Bacterial Viruses
    628 words
    Viruses are infectious agents found in almost all life forms. The viruses are made up either of DNA or RNA, surrounded by a capsid, a protein coat. Viruses are between 20 and 100 times smaller than bacteria, or about 450 nanometers (. 000014), being the largest, to 30 nanometers (0.000001 in.) being the smallest which make them virtually impossible to be seen by light microscopes. Viruses often damage or even kill the cells they infect. They reproduce by releasing their nucleocapsid, or a copy o...

  • Acute Leukemia Causes
    490 words
    Leukemia Leukemia is a disease that affects blood-forming tissues, mainly bone marrow. Leukemia also affects the lymph glands and spleen. Leukemia causes the body to produce an extreme amount of abnormal white blood cells. This causes infections because the abnormal cells cannot stop infections like the normal cells do. Leukemia also causes anemia. Anemia is a disease in which the body makes less blood cells. This happens because the leukemic cells crowd the system. Leukemia also causes excessiv...

Thus, the four major types of leukemia are acute or chronic myelogenous leukemia and acute ...
  • Identification Of The Abnormal Gene

    Cystic Fibrosis Cystic Fibrosis, is a genetic disorder of the exocrine glands, affecting children and young people; median survival is 25 years in females and 30 years in males. It is caused by a genetic abnormality in the CF trans membrane conductance regulator (CFTR) gene that results in the disruption of chloride transfer across cell membranes. As a consequence, chloride ions build up in the cells of the lungs and other organs. Water stays inside the cells to dilute the chloride rather than b...
  • Mitochondria Dna Rearrangement And Base Substitution Mutations
    662 words
    Mitochondria are the powerhouse of the cell. Their sole responsibility is to provide energy for the cell. They do this by synthesizing a molecule known as ATP, which the cell uses as energy. Mitochondria are different from the rest of the cell organelles because they contain their own DNA outside the nucleus. Mutations in this DNA have been found to be linked to Alzheimer's and other neurodegenerative diseases. Mutations in the DNA cause the mitochondria to function in other ways than it usually...
