Unwrapping DNA for Ancestry Testing
Science has enabled the DNA of human beings to be tested for various reasons. The term DNA actually refers to a part of chromosomes of living organisms. The initials stand for deoxyribonucleic acid. It is a component of chromosomes that has the ability to self-replicate from one generation of the organism to the other. Replication enables people to be able to use DNA as a method for testing for relations withing living beings.
A DNA test can help to unearth many things about living organisms especially human beings. The most common of them is paternity testing. Cases that require paternity testing in the world are many hence the popularity of this type of DNA testing. DNA paternity tests are tests done on a child and a man to test whether the child is actually a biological child of the man. DNA testing is an almost 100% certain test for paternity in the world today.
Other aspects about human beings can be established by testing DNA. Though not common, these phenomena are very important about human beings. One can establish the ancestry of human beings using DNA tests. This can be done using a genealogical DNA test. This type of test usually examines a person’s genome after unwinding the strand of a DNA chromosome. DNA strands are usually unwound during testing.
Genealogical DNA testing can help establish different results. First of all ethnicity can be established. Ethnicity in this context refers to the tribe. It refers to people of common descent who have one unifying factor such as a common language. Having established which tribe one comes from, it is then easy to use the information to establish the ancestry of the person.
One can test the origin of certain fossils by testing DNA ancestry. Scientists have been working hard to establish many aspects of the origin of man. Remains of human beings form an important parcel in this investigation. They use DNA testing to further investigate relationship of such remains with the modern world. Such facts can then lead us to conclusive information about ancestry.
The geographical origin of any species can be established by using genealogical tests. The age of remains of human beings can also be established though with approximation from such genealogical DNA tests. How does DNA testing happen and which part of the human body can be used for chromosome extraction and testing? Well, most times, blood is used in DNA testing. However, there are other parts of the body that can be used in place of blood. For instance strands of human hair have been found to contain genetic chromosomes that can also encode ancestry genes. Scientists have established that one can uses saliva as well as other body fluids to carry out DNA tests.
