Neha dna screening

  1. 1. DNA Screening Ericka and Neha
  2. 2. DNA Screening • Genetic Testing • Deoxyribonucleic Acid • The information coded in our DNA is used to make proteins • Each section of DNA that codes for protein is called a gene. • • The technology we have now as DNA screening, are test doctors run on you to see if you have series of genes that are related to certain diseases. Sections of DNA that scientist can follow throughout cell division are called DNA markers. • When some mark changed they said it was because the DNA was changing this was related to the cell’s environment. For example, if someone had a gene that increased the chances of getting a certain disease, if they change the cell’s environment it could potentially change the gene Even cancer treatment can involve DNA screening In simple words, DNA screening looks at someone's genes and determines if they may or may not have a genetic disorder.
  3. 3. Benefits and Drawbacks PROS • • • • Diseases would be easier to handle. Helpful to identify a missing relatives, parents or kids. Can use any parts of your body for testing. (blood, saliva, hair etc.) Helpful for crime investigations. CONS • • • • • Expensive. The Anxiety of living with the knowledge of having a very severe disease and it may be a burden. Confidentiality has become a problem. Innocent people could hold accountable for a crime they didn’t do. Results may take time and may not be accurate.
  4. 4. Social, Political, and Ethical Issues Social A huge issue for individuals to encounter because other people (strangers) may use your DNA information. Privacy Wrong Accusation Reunite Depression Innocent people had been called guilty for a crime that they didn’t committed. DNA screening may helped find missing love one. The stress an individual may experience form knowing that he/she have a severe disease.
  5. 5. Social, Political, and Ethical Issues Political Employers may not be hired because of he/she’s genetic makeup and think you are not suitable for the job. Employment Unfair Treatment More jobs Intruding Insurance companies can fully deny you or charge you more because of the disease you have. More money is going into genetic testing research which makes more jobs available for it. Anyone can trace you down by taking your saliva from your coffee cup etc.
  6. 6. Social, Political, and Ethical Issues Ethical Decision making These test could informed parents if they have a normal child or not, and if they don’t they could try to alter the DNA to have a perfect child and assort ones that are not. Take advantage May be used to harm others like to create a crime or other wrong proposes. Responsibility Discrimination A job interview would consist of a crime sample that is screened for your genetic makeup-which is essentially your identity. Due to “bad” genes.
  7. 7. How is the procedure especially as it relates to determining performed How DNA screening works can be a bit complex, human identity. Process 1 Medical geneticist, primary care doctor, specialist or nurse practitioner orders the test. Often done as a part of a genetic consultation. Process 3 Process 2 The test are performed on a sample of blood, hair, saliva or other tissue. The sample is sent to a laboratory where our scientists use a technology called Polymerase Chain Reaction to create a lot of copies of the specific portions of the DNA. Process 4 Also, to look for specific changes in chromosomes, DNA or proteins depending on the suspected disorder.
  8. 8. How is the procedure performed Process 6 Process 5 The Polymerase Chain Reaction uses precise heat and a chemical cocktail to cause the DNA to replicate itself. Once the scientist have enough replicated DNA, they run the samples on a ABIPRISM 313OXL Genetic Analyzers, and determines your DNA information. Process 7 The scientist reports the test results in writing to the patient’s doctor or genetic counselor. In addition, before a person has a DNA test, it is important that he or she understands the testing procedure, the benefits and limitations of the test, and the possible consequences of the test results.
  9. 9. How does it improve the well-being of our society • The DNA screening can provide • Help alleviate the process and information about diagnosis treatment, managing, or the perpetrator of an illegal prevention of a disease that will action by examining genetical be helpful. • time of deduction to determine evidences from the scene. Individuals to obtain knowledge • Also helps minimize the risk of of his/her own genetic disease or false accusations and susceptibility which preventive deformation of innocent interventions can be individuals on atrocity. anticipated. • The satisfactory of human needs to other health services will become a matter of justice.
