Case Analysis - Week 3

Running Head : CASE ANALYSESCase Analyses on some working in lore and ethics[Author][University]Case Analysis 1 : DNA is the molecule of heredityFrom Gregor Mendel s possibleness of existence of gene and their transmission from contemporaries to generation , to Friedrich Mischer disc everyplacey of DNA the creation of Watson-Crick Model leading to the onward motion of inherited engineering , biotechnology and cloning . These are among the diachronic reasons that DNA is indeed the molecule of transmittable Furtherto a greater extent , the close to conclusive evidences in support of DNA as the communicable material came from the following three ways : transformation of bacteria , mode of infection of bacteriophage and conjugation of bacteria . In 1928 , Frederick Griffith encountered phenomenon known as catching transformation . Oswald Avery , Collin Macleod Maclyn McCarty also gave evidence that DNA was the physical material for heredity ADDIN EN .CITE Verma20043 336P .S VermaCell biota ,Genetics , Molecular Biology : Evoloution and environmental science2004S Chand (Verma , 2004 Other scientists that contributed for the discovery of DNA and heredity are Altmann , Albrechi Kossel , Walter J anes , Franklin W .

Microbes served as the sources of progress of discoveries or so the secrets and wonders of heredity . As the years passed , scientist learned how to control the processes of hereditary and protein synthesis to benefit our daily lives . It gave us much luck leading to genetic engineering and biotechnology ADDIN EN .CITE AlcamoEdward AlcamoMicrobes and orderliness : An Introduction to Microbiology2003 Jones and bartlett Publishers (Alcamo 2003 . This scientific processes soon became a serviceable technology from selective breeding , genetic engineering to biotechnology and cloningCase Analysis 2 : acquirement is cumulativeThe history of light and for scientists , one of the fulfillment of the work of s massacre is the sense of continuing a great historical tradition of carrying forward the work of predecessors and preparing the primer of successor ADDIN EN .CITE Laura GarwinLaura Garwin , Tim LincolnA Century of character : Twenty-One Discoveries that Changed Science and the innovation2003Univers ity of Chicago Press (Laura Garwin , 2003 . In the early 1900s , W . Johannsen , H Nilsson-Ehle , E .M . East and R .A . Fisher tied the proper(postnominal) relationships of Mendelian genetic science to biometrical approaches to develop the basis of quantitative genetics . In 1902-1903 , on the other hand , Walter S . Sutton and Theodor Boveri associated Mendel s results with carrelular phone meiosis to explain Mendel s results , thereby connecting two independent disciplines , genetics and cytology to develop the chromosomal theory of inheritance ADDIN EN .CITE DunhamRex A DunhamAquaculture and Fisheries biotechnology : Genetic Approaches2004CA BI Publishing (Dunham , 2004 . These are among those proofs that science is progressing be work , at each moment in time , reliable theories are a better approximation and a more factual evidences to nature s laws than past theories . However , Kuhn rejects the notion that science is cumulative in the sense that a new theory is necessarily an improvement on the one it replaces . He finds that science changes not in an evolutionary fashion but in a serial of revolutions in which the world view of the members of the scientific community is significantly changed ADDIN EN .CITE ColeStephen ColeMaking Science amongst Nature and ships company1992Harva rd University Press (Cole , 1992Case Analysis 3 : genus Cancer query toll and the impact to societyScientific research costs money , time and social movement because of this , there is the need to acquire funds , be it a government or a private fund , to knock against the costs for research raise ethical issues for the scientists or researchers . Decisions regarding mount have many implications . Such decisions should have a full-blooded impact on society as well as major impact on the career development and essential have a huge contribution to knowledge , in this case , in the field of science and medicine . It depends on the societal priorities that makes some areas of research are preferentially back up over others ADDIN EN .CITE Deni Elliott199788 86 Deni Elliott , Judy E Stern search Ethics : A Reader1997UPNE (Deni Elliott , 1997 Cancer , being the or so feared of all diseases , often associated with anxious(p) , making it as second most common cause of remnant in the U .S . Unlike other sea wolf disease , cancer usually causes a slow death involving pain suffering , psychological distress , financial incumbrance upon long-term therapy and a feeling of hopelessness . Because of this , billions of dollars have been invested over the years in cancer research . Despite the capacious effort to fight for cancer , the number of new cases of nearly every form of cancer continues to persist . Cancer research and interference are extremely complex fields of consume because the exact nature of the single cancer jail cell is so hard to pin down with has many different causes ADDIN EN .CITE Simone9996Charles B SimoneCancer And Nutrition : A Ten-Point proposal to Reduce Your essay of Getting CancerB . Jainist Publishers (Simone Most antineoplastic agents are sort according to their structure or cell cycle bodily process . Two major classes of che takeapeutic agents have been established : cell cycle stage-specific and cell cycle phase-nonspecific agents . Cell cycle phase-specific agents kill actively dividing cells only into a specific phase of the cell cycle (phases G1 through phase M . For example , vincreastine and vinblastine , are lethal only to cells in the M phase , while hydroxyurea and cytosine arabinoside inhibit DNA synthesis by targeting the S phase . Because phase-specific agents depend on cells being in a specific phase to work , they are most effective against cells that are rapidly make pass . Rapid cycling ensures that the cell passes through the phase in which it is vulnerable to the cause of drugs ADDIN EN .CITE Margaret Barton-BurkeMargaret Barton-Burke , Gail M WilkesCancer Therapies2006Jon es Bartlett Publishers (Margaret Barton-Burke , 2006 .

However , treatment resistance in cancer do exists which is related to the genetic diversity of the cancer cell universe caused by series of mutation in a genetically unstable population making it vulnerable to effective intervention ADDIN EN .CITE crowd together H Goldie1998111 1116James H Goldie , Andrew James Coldman medicine Resistance in Cancer : Mechanisms and Models1998Cambri dge University Press (James H . Goldie , 1998Case Analysis 4 : Ethical issues of antenatal interrogatory (amniocentesisAmniocentesis is a prenatal testing for the detection of chromosomal defects . It is usually performed between 16 and 20 weeks gestation as an outpatient procedure which only takes up about 20 minutes ADDIN EN .CITE TravisCheryl Brown TravisWomen and Health Psychology : Biomedical Issues1988Lawren ce Erlbaum Associates (Travis , 1988 . A variety of genetic conditions can be set through amniocentesis , including single gene diss , such as cystic fibrosis , chromosomal abnormalities (e .g . Trisomy 21 , and biochemical or metabolic diss such as TaySachs disease . It is central to take into account that prenatal testing is performed to identify fetuses at guess for a genetic dis and to identify fetuses at risk for poor prenatal outcomes . The main difference is that , the former usually does not have a curative intervention for sale to favorably correct the outcome , while the latter testing is done because there is an appropriate therapy that can positively exercise fetal /infant health and well-being . This is an important preeminence given it has long been held that the mother has the rightly to choose or not choose to have prenatal genetic testing performed on the fetus . The legal system has upheld the only right to the woman to choose the outcome of the pregnancy . For most genetic diss identified through prenatal diagnosis , the mother and her partner are given with the choice of whether to continue or discontinue the pregnancy and if continued raising or self-aggrandizing for adoption a child with minor to severe contrary effects on growth and development ADDIN EN .CITE Lachman Vicki D Lachman apply Ethics in Nursing2006Sprin ger Publishing (Lachman , 2006ReferencesADDIN EN .REFLIST Alcamo , E (2003 .
