DNA Testing - An Overview Of This Revolutionary Scientific Breakthrough
What is DNA testing? It is
specified testing that searches for the absence or presence of DNA sequences. It
makes use of molecular methods like DNA chips, arrays, or polymerase chain
reaction. Your genetic makeup is carried inside your cells nucleus, which
contains the DNA material.
Deoxyribonucleic acid is the scientific terminology for DNA. DNA determines the
cells behavior, function, and structure. What is great about DNA is that not
only can it tell the identity of a person, but it can also give information
about four thousand genetic conditions and diseases.
There are a variety of samples
that DNA testing can be conducted on. For example, semen, tissue, cheek cells,
and blood cells all contain DNA. Every person has DNA that is both distinct and
unique to only him or her. There is one exception however, and that is with
identical twins. DNA can be compared to our individual fingerprints, thanks to
the specific nature of DNA testing, paternity can be established. The courts use
this method because the results of the tests are generally ten to one hundred
times the accuracy required by the courts.
There are advantages and disadvantages to undergoing DNA testing. For example,
DNA testing is typically not covered by insurance. Even though we have laws in
place that are designed to protect us from health insurance discrimination, many
people believe that the results of genetic testing may affect their chances of
obtaining insurance coverage.
Family dynamics is an area of major concern for many people. For most families,
the genes within the family are considered to be an heirloom. Therefore, this
revolutionary testing might have some negative impact on the family.
Furthermore, the testing might reveal relationships that were previously
unknown, perhaps paternity, or maybe even reveal family secrets.
This testing can have different types of effects on people both before and after
the tests have been conducted. Therefore, it is wise to obtain professional help
to deal with these issues and feelings.The government and courts rely on DNA testing in solving crimes and finding
leads. The method of DNA collection have proven guilt in crimes, as well as
proven innocence in some wrongly accused of serious crimes or felonies.
You might likely see some advertisements for home DNA testing kits. It is
important to remember that they often make promises that they cannot keep. The
internet plays host to some of these sales and you could look at paying between
$100 and $1,000 to purchase the kits. The General Accountability Office (GAO)
states that these tests essentially create predictions that have been unproven
medically and fail to provide meaningful information.
The United States FBI is wanting to keep a database nationally of DNA. There is
a large amount of controversy surrounding this; many feel that obtaining DNA
from any person without first gaining permission is going too far. It is far too
easy for them to obtain DNA from a coffee cup or toothbrush.
Summary:
There are advantages and disadvantages to undergoing DNA testing. The government
and courts rely on DNA testing in solving crimes and finding leads. The method
of DNA collection have proven guilt in crimes, as well as proven innocence in
some wrongly accused of serious crimes or felonies.
