It is also responsible for the advancement of the
several biological fields like applied genomics, immunology, development of pharmaceutical therapies and
diagnostic test and recombinant gene
techniques.
Other specialized blood tests that detect DNA of the organism, such as Polymerase Chain Reaction (PCR) a
technique used in molecular biology to amplify a single copy or a few copies of a piece of DNA across
several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence and serologythe scientific study or
diagnostic examination of blood serum, especially with regard to the response of the immune system to pathogens or introduced substances, are helpful.
