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.
