Question

when is dna test done?

Answer 1

DNA paternity testing is the use of DNA
profiling (known as genetic fingerprinting) to
determine whether two individuals are
biologically parent and child. A paternity test
establishes genetic proof whether a man is
the biological father of an individual, and a
maternity test establishes whether a woman is
the biological mother of an individual. Tests
can also determine the likelihood of someone
being a biological grandparent to a grandchild.
Though genetic testing is the most reliable
standard, older methods also exist, including
ABO blood group typing , analysis of various
other proteins and enzymes, or using human
leukocyte antigen antigens . The current
techniques for paternity testing are using
polymerase chain reaction (PCR) and
restriction fragment length polymorphism
(RFLP). Paternity testing can now also be
performed while the woman is still pregnant from a blood draw

Answer 2

DNA fingerprinting is a chemical test that shows the genetic makeup of a person or other living things. It's used as evidence in courts, to identify bodies, track down blood relatives, and to look for cures for disease.
