    Synthesis Essay On Tobacco

    • 1544 Words
    • 7 Pages

    The detrimental health affects caused by smoking tobacco have long been known in our society. Tobacco smoke is composed of a complex, chemical mixture of roughly 60 known carcinogens (Alexandrov, et al., 2016). Smoking tobacco and exposure to other carcinogens increases human risk for cancer significantly by enhancing DNA mutation rates. Different carcinogens cause slightly different types of DNA damage in humans that eventually lead to cancer (Ehrenberg, 2016). These unique patterns of…

    Gene Mutations Gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations are affected by the change in the DNA sequence. There can be many different types of mutations. (Department of Genetics, Stanford School of Medicine, Para I) Some examples are point mutations, missense mutation, nonsense mutation, frame shift mutation, silent mutation, deletion, insertion, and duplication. (US National Library of Medicine) These mutations can either occur naturally or actually…

    Neurodegenerative disease is an all-encompassing term for an array of conditions which principally affect the neurons of the human brain. These make up the nervous system, which also incorporates the spinal cord and, under normal circumstances, do not replace themselves or reproduce. Therefore, when they are damaged or die off, they are unable to be replaced. Neurodegenerative diseases are debilitating conditions that result in progressive degeneration and/or the death of nerve cells. This…

    Sickle -cell anemia is a disease that affects the shape of red blood cells and it causes them to become a sickle shape. Sickle cell anemia was first noticed around 1670, in a tribe called Krobo in Ghana, Africa. In 1910 a physician in Chicago named James Herrick was the first person to first describe it clinically (Kiple). Since then much more information has been discovered on this disease. Such as this is a disease that people inherit from their parents if both are carriers. There are many…

    degeneration of brain cells. It is a complex disease that affects specific areas in the brain, one particular is the the motor area. The degeneration of brain cells is caused from a genetic mutation in DNA during DNA synthesis. The defect causes cytosine, adenine, and guanine (CAG) to repeat over and over again in DNA sequencing. With each generation that develops HD the mutation may expand further causing more CAG sequencing in future generations. Currently there isn’t any way of determining…

    Most people could probably guess that heart disease and cancer are the leading causes of death, but many may not know that strokes are the fourth leading. Strokes are also one of the leading causes in long-term adult disability. A stroke occurs when there is a clot in a blood vessel or an artery located in the brain, interrupting or severely reducing blood flow to the brain, preventing it from getting the oxygen it needs. There are two different types of strokes, and there are multiple types…

    The 2009 Nobel prize for Physiology and Medicine was awarded to Drs Elizabeth Blackburn, Jack Szostak and Carol Greider for their discovery of telomeres and telomerases; but what are they and why did the Nobel prize committee find their discovery so important? Drs ezilabeth Blackburn, Jack Szostak and Carol Greiders discovery of telomeres and telomerases can be considered as one of the key milestones in our understanding of DNA replication in eukaryotes as they helped us figure out how the…

    parents. The DNA in a person is a combination of the DNA from each of their parents. DNA has a double helix shape, which is like a ladder twisted into a spiral. Each step of the ladder is a pair of nucleotides. The four nucleotides in this ladder are adenine (A), thymine (T), guanine (G), and cytosine (C). The nitrogen bases are found in pairs. 'A' only pairs with 'T', and 'C' only pairs with 'G'. The bases are held together…

    innovations. Part of these innovations was the understanding of how DNA works and can be utilized for specific purposes. In one article, DNA is comprised of four letters which each represent a certain chemical. These chemicals include thymine, cytosine, adenine, and guanine. The four chemicals bind to each other to form chains that specify which amino acids will be needed to complete a protein (“Definition of Genetic Code”). Another source states that all living creatures share the exact same…

    Discuss the mechanisms involved in the development of Hereditary Haemochromatosis. Hereditary Hemochromatosis is a genetic Disease, which in short term is known as HH. Even if Hereditary Hemochromatosis is a genetic disorder, it’s a disease that can be treated easily. HH is a Disease that has a change in the way that our body works to regulate iron absorption. Iron is an important component in our body, which is required by all cells. Normally the required iron for the cells goes from the…
