When there is a question of paternity in an unborn child, you may wish to have a prenatal paternity test performed in order to determine the actual father of the child. Just like a paternity test that is done after a pregnancy, the test will compare the DNA of the mother, the unborn baby and the supposed father in order to establish paternity.
DNA comparisons have been performed since 1953 when it was discovered that we all have DNA and that there is a specific pattern for each individual.
Under a microscope, DNA looks very much like a ladder that has been twirled and twisted. It is composed of four base molecules. These are Adenine, Thymine, Guanine and Cytosine. These molecules bond with the sides of the DNA strand and are actually known as Hydrogen Bonds. If you want to collect the information about the DNA testing in New York then you may search for DNA Testing In Buffalo NY and Paternity Test In Buffalo NY online and get the details.
Depending upon the way that these molecules are configured is what is responsible for the way we look, think and even act. These are hereditary traits. There are markers present from both parents' DNA and comparing the DNA of the mother and father with that of a child will determine if the father is the biological father or if he is not.
There are two different types of paternity tests which can be done before a child is born. They are both invasive and for this reason, there is a small risk associated with both procedures. This should be thoroughly discussed with your physician if you are considering it.
The two types of prenatal paternity tests include Chorionic Villi Sampling or CVS and Amniocentesis. CVS is the test that physicians use to establish paternity when the mother is 10 to 13 weeks pregnant. The doctor extracts cells from the placenta which surrounds the fetus. An ultrasound is used to help the doctor retrieve the cells.
