TRANSCRIPT
DNA ScreeningEricka and Neha
• 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.
• Genetic TestingDNA Screening
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
In simple words, DNA screening looks at
someone's genes and determines if they may or may not have a genetic
disorder.
Even cancer treatment can involve DNA screening
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.
• 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.
CONS
Benefits and Drawbacks
Innocent people had been called guilty for a crime that they didn’t committed.
DNA screening may helped find missing love one.
Social, Political, and Ethical IssuesSocial
A huge issue for individuals to encounter because other people (strangers) may use your DNA information.
The stress an individual may experience form knowing that he/she have a severe disease.
Privacy
Wrong Accusation
Reunite
Depression
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.
Social, Political, and Ethical IssuesPolitical
Employers may not be hired because of he/she’s genetic makeup and think you are not suitable for the job.
Anyone can trace you down by taking your saliva from your coffee cup etc.
Employment
Unfair Treatment
More jobs
Intruding
May be used to harm others like to create a crime or other wrong proposes.
A job interview would consist of a crime sample that is screened for your genetic makeup-which is essentially your identity.
Social, Political, and Ethical IssuesEthical
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.
Due to “bad” genes.
Decision making
Take advantage
Responsibility
Discrimination
How is the procedure performed How DNA screening works can be a bit complex, especially as it relates to determining human
identity.
Process 1Medical geneticist,
primary care doctor, specialist or nurse
practitioner orders the test.
Often done as a part of a genetic consultation.
Process 2The test are
performed on a sample of blood, hair, saliva or other tissue.
Process 3The 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 4Also, to look for specific
changes in chromosomes, DNA or proteins
depending on the suspected disorder.
How is the procedure performed
Process 5The Polymerase Chain Reaction uses precise heat and a chemical cocktail to cause the
DNA to replicate itself.
Process 6Once the scientist
have enough replicated DNA, they run the samples on a
ABIPRISM 313OXL Genetic Analyzers,
and determines your DNA information.
Process 7The 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.
• The DNA screening can provide
information about diagnosis
treatment, managing, or
prevention of a disease that will
be helpful.
• Individuals to obtain knowledge
of his/her own genetic disease
or susceptibility which
preventive interventions can be
anticipated.
• The satisfactory of human needs to other health services will become a matter of justice.
How does it improve the well-being of our society
• Help alleviate the process and
time of deduction to
determine the perpetrator of
an illegal action by examining
genetical evidences from the
scene.
• Also helps minimize the risk of
false accusations and
deformation of innocent
individuals on atrocity.
