Introduction Transformation is a genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material from its surrounding through the cell membrane. The arabinose operon changes AraC from a repressor to an activator; in this experiment the pGLO plasmid has been designed with a modified operon so that in the presence of the arabinose the bacterial cells which have been transformed by the pGLO plasmid will fluoresce due to the production of GFP.

effected‚ and through sex. Hepatitis does not cause long term infection. If you had it once you cannot be infected with the virus again only other types as in hepatitis B or C. The immune system in your body tries to fight the disease by using its antibodies. Not everyone who is infected with the hepatitis A virus will experience symptoms. Some kids and babies infected with the disease do not have any symptoms at all. But those who experience symptoms may have yellowing of the skin‚ eyes‚ and fingernails

Question: A patient is admitted for electroconvulsive treatment (ECT). The physician orders the neuromuscular blocking agent metocurine iodide (metubine) to reduce trauma by relaxing skeletal muscles. Explain the process of muscle contraction and how a neuromuscular blocking agent‚ such as metubine‚ would interfere with muscle contraction. Aaron arrived at the hospital with the following symptoms: drooping eyelids; fatigue and weakness of his muscles; and difficulty talking‚ breathing and swallowing

Do you think that even if your immune system is the healthiest of all‚ you won’t get influenza? Well‚ you are totally wrong. Anybody can get the flu. The best way to prevent it is getting the flu vaccinations. You should never take risks for infections. The most common reasons people don’t get the vaccinations are because they think they are totally healthy‚ they think that they never got the flu so they won’t ever get it‚ they are tough‚ the flu shot made them sick‚ and last but not least‚ the vaccinations

HIV AND AIDS Definition AIDS or acquired immunodeficiency syndrome - was originally defined empirically by the Centers for Disease Control and Prevention(CDC) as “the presence of a reliably diagnosed disease that is at least moderately indicative of an underlying defect in cell-mediated immunity.” Following the recognition of the causative virus‚ HIV‚ and the development of the sensitive and specific tests for HIV infection‚ the definition of AIDS has undergone substantial revision. The current

long-term with periods of activity and then remission. Lupus is a disease that attacks your own body. The immune system is the body’s natural defense against disease. In lupus‚ the immune system‚ which is designed to protect against infection‚ creates antibodies that attack the body’s own tissue and organs. Lupus can affect almost any part of the body‚ most often the kidneys‚ skin‚ joints heart‚ lungs‚ blood and the brain Some people with lupus experience serious life-threatening problems. But for most
