If you can get a swab from the inner cheek of the mouth and put it into a sterile tube, you can get it checked out. But..there may be legal reasons you should look into first.
DNA can be found on any part of the body. My best bet would be to get a piece of hair.
can be done prenatal.
Get something with his DNA on it, like hair from his hairbrush. It has to have the roots still on it.
Yes its called a fetal cell/dna prenatal paternity test
They predicted that the DNA double helix would unzip and replicate semiconservatively.
Yes, all you need is something with his DNA on it like a hair with the roots still on it from his hairbrush for instance.
No. well, actually prenatal DNA tests are done all the time, google it....
a DNA test, or before birth you can have a test called a prenatal test, and it will tell you if your baby has inherited a disease.
Non invasive prenatal paternity testing can be done by collecting a blood sample from the mother. Fetal DNA makes its way into the maternal blood stream through the placental wall which envelopes the unborn baby. A particular vein has been found to be particularly rich in fetal DNA. This procedure carries huge advantages over prenatal testing procedures such as amniocentesis or CVS. The non invasive prenatal test is totally risk free.
The only way to determine paternity is through DNA. The easiest, least expensive way to do that is with a cheek swab. Epithelial cells are used as the source of DNA. There is no "home test." The swabs are sent to a lab where the process takes several days or weeks. You could get DNA through other means, (hair sample, e.g.) but it would be far more expensive. The cheek swab is the most accessible method.
Scientists are able to study specific genes.
Not necessarily. You can trace back your family tree with good research. You may be able to go back hundreds of years. It depends on how far you want to be able to go back. DNA may only be of use if you have other people to test. You can't really do that without knowing who to test. That will take some research to find out who might be related to you. So you will need to do your research, with or without DNA.
