The Power of DNA Analysis

In the world of medicine and disease there is one disease that is as well known as it is deadly: Cancer. Many people understand the severity of cancer and how it attacks the immune system and ultimately can kill a person. The war on cancer was started in 1971 by President Nixon and this set of four decades worth of study and has lead to a large amount of information being learned about the cancer genome. A new strategy has recently surfaced and is gaining ground, DNA analysis of the cancer-ridden cells. In order for a cell to become cancerous it usually under goes a mutation to its genetic code. It then begins to grow and multiple without stopping. It than begins to invade or take over other cells those causing the cancer to spread. A cell can become cancerous through many different factors, a constant exposure to tobacco or ultra violet rays or even an inherited genetic anomaly. What doctors would traditional do is fight the cancer with chemotherapy or by trying to remove the tumor with knives and lasers. Usually this could lead to some controversy because this type of treatment is generalized and does not work well for the specific cases. Cancer is typically attacked with the same drugs and procedures and is the same for each patient. The type of cancer or the specific patients case generally does not affect the process and this can cause the cancer to return in some cases. The traditional method can be effective in many cases but is not a guaranteed cure.
Scientists are now using DNA analysis to translate the DNA ATGC sequence. They use this to help find out what is the actual cause of the mutations that create the uncontrollable cell division. By looking at the genome of the DNA they can find out the cause and make specific treatments. This differs from the traditional treatment because the traditional method was generalized and not specific to the patient. DNA analysis can

    DNA stands for Deoxyribonucleic acid and looks like a spiral. The spiral is also known as a double helix. The strands are made up of our genetic information, composed of genes and chromosomes. There are four bases divided among purines and pyrimidines. On the purines there are Adenine (A) and Guanine (G). On the pyrimidines there are Cytosine (C) and Thymine (T). The base pairs are Adenine and Thymine (A-T) and Cytosine and Guanine (C-G). DNA is found in the nucleus of every human cell. Humans have 46 chromosomes. When a cell reproduces, the chromosomes get copied and distributed to each offspring.…

    The flow of information starts with transcription. Within transcription, the DNA molecule holds a nucleotide sequence called the promoter that the RNA polymerase attaches to and begins the RNA synthesis. Through the process of transcription, the RNA strand becomes longer and finally detaches from the DNA strand, wherein the two DNA strands come back together forming the previously continuous strand. At this point the RNA turns…

    DNA is typically has two strands running in opposite direction and is usually referred to as a double helix. Each on the individual strands consists of a backbone that is formed by sugar molecules linked together in groups. Each individual sugar molecule is covalently linked to one of the following possible bases: Adenine, Guanine, Cytosine and Thymine. These bases are typically aligned perpendicular to the axis of the strand. As previously stated the strands run in opposite directions with the bases paired up with Adenine always with Thymine and Guanine always with Cytosine. Theses pairs form hydrogen bonds with the A/T pair having 2 and the G/C pair having 3. The extra hydrogen bond makes the G/C pair stronger.…

    Describe the structure of DNA.DNA is thread formed by two strands, related together to form a double helix. The double helix looks like a twisted ladder. The sides of this ladder are long unites called nucleotides and are made of three parts; a nitrogenous base, a sugar, and a phosphate group. The sides of the ladder or the nucleotides from the two separate strands of the DNA are attached by an appendage made of one of four separate bases. These appendages represent the rungs of the DNA ladder and are attached to the complimentary strand of the DNA. The bases or rungs are made of either Adenine (A) OR Thymine (T) or Cytosine (C) and Guanine (G). The attachment of the strands by the bases is specific Adenine can only join with Thymine, and Cytosine can only join with Guanine. Since this base pairing is specific, if one knows the sequence of bases a long one strand of the DNA one will also know the strand of the DNA one will also know the sequence along the complimentary strand.…

    DNA is a structure of specific molecules and a complex mixture of chemicals. DNA is a nucleic acid, which is a group of complex compounds that can be found in all living cells or viruses, and controls cell health and function. Nucleic acids are composed of polymers and monomers, which are referred to as nucleotides. There are four different types of nucleotides that make up the structure of DNA, which are abbreviated A, C, T, and G. Covalent bonds join together nucleotides through sugar and phosphate. Polynucleotides, or a polymer nucleotide, which tends to be longer than a monomer nucleotide, contains many variations of arrangements of A, C, T, and G.…

    Forensic serve both the living and the dead -- those who are victims, suspects, survivors, and those who are left behind. Forensic nursing blends nursing science with medicine, law, and criminology. At its core, this specialty seeks to address healthcare issues that have a medico legal component. Long before holding the designation of forensic nurse, nurses provided care to the victims and perpetrators of violence. History reveals that in the 14th century, performed gynecologic examinations for evidence of pregnancy or virtue, and then testified before the King's court. Forensic nurses do not replace other forensic professionals, but instead bring a unique nursing perspective to the multidisciplinary forensic team.…

    During the surgery the area of cancer is being examined as well as the organs around the area of the growing cancer. Curative surgery may only be used if the area of cancer can be removed altogether. In cases like this surgery is the only treatment and it is the only form of getting rid of the cancer cells. In other cases doctors are unable to remove that tumor completely and they may only be able to remove parts of the tumor so it does not destroy organs that are nearby or tissue that is nearby; this type of surgery is called debulk surgery. After being able to remove parts of the tumor or growing cancer cells doctors add other treatments to cure cancer that, that person is experiencing. Usually the type of cancer that lets doctors remove part of the cancer cells is ovary cancer then the person experiencing the cancer maybe recommended other treatments. Some people maybe farther advanced in their cancer stage and doctors use palliative surgery in order to help the person with the cancer to feel better. Doctors use this type of surgery in order to reduce a pain someone might be experiencing; this type surgery is not to help heal or cure that cancer it is to remove any blockage…

    First of all, the malignant tumor is life threatening unless it treated. It, also known as, cancer tumor, is additionally defined by its invasion of local tissue and its ability to spread to other parts of the body. The tumor grows and spreads faster into surrounding tissues. It is diagnosed by examination of their vascularity, shape and form of cells division. The most common form of malignant tumor is lung cancer. However, the treatment depends on the type and stage of the tumor after diagnosis. While some cancers can be cured, some of them are unfortunately incurable.…
