The Debatable DNA Testing - Discovering The Role Your Genes Play
How do you define DNA testing?
It is specified testing that looks for the absence or presence of DNA sequences.
It makes use of molecular methods like DNA chips, arrays, or polymerase chain
reaction. Your genetic information 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. Because DNA testing is
becoming cheaper, this is the most popular form of testing.
There are many uses of DNA
testing. For example, to establish paternity DNA is often used. Paternity can
also be established in an unborn child. This is done with amniocentesis or CVS
(Chorionic Villi Sampling). The latter test is generally done in the early
stages of a pregnancy between ten to thirteen weeks along.
To conduct the tests, the obstetrician will insert a needle into the abdomen of
the mother. Another method is to vaginally insert a catheter with the aid of
ultrasound, to collect the cells. To conduct the amniocentesis test, the
obstetrician must collect fluid via the uterus, with the aid of ultrasound to
guide them. This test is typically performed at weeks fourteen through
twenty-four. Because these procedures are invasive, they should be thoroughly
discussed with the obstetrician.
Breakthroughs with DNA testing happen regularly. For example, now DNA tests can
be useful when trying to determine your ancestry. You see, our DNA comes from
both of our parents. In general, most areas of our DNA go through dramatic
changes. However, there are some areas of the DNA do not change at all. Because
of the changes and the things that do not change, the testing is able to link
many generations together and reconstruct the history of families.
DNA testing has also become popular with those who have been adopted. This
allows them to trace their ancestors and find biological parents. To perform
this kind of testing, a doctor will typically rub a cotton swab on the inside of
the patient's mouth. It is painless, easy, and quick, so this means even a baby
can undergo this testing. The cheek contains DNA within the skin cells and after
rubbed in the mouth, it will be on the cotton swab. Then the swab is sent to the
laboratory to test the cells, analyze the DNA in the cells, and determine if
there is a match within that family.
DNA is also used to solve crimes of a serious nature. DNA testing has been used
to prove guilt or innocent in those that stand accused of felonies and serious
crimes. DNA is also used, thanks to new technology, to determine an unborn
child's sex. This test uses the DNA in the blood of the mother to define the sex
of the child, because of the genetic fetal chromosomes found within the blood.
This test can be before from week five and on in a pregnancy.
Lastly, DNA testing has been used to conduct an evaluation of health risks and
health. The tests can even aid a person in weight loss by defining foods they
crave.
Summary:
Deoxyribonucleic acid is the scientific terminology for DNA. DNA determines the
