How do DNA Tests work?
• What are the applications of DNA Testing? • How accurate is DNA-Based paternity testing? • Do I need permission from a doctor or lawyer to have a paternity test done? • Who has to have a sample taken? • What if one of the parents is deceased? • Is there any legal confidentiality policy adopted in America that ensures privacy of DNA testing results? • How is Red blood grouping testing and HLA testing different from DNA paternity testing? • Can DNA testing be done before the baby is born? • Can I preserve DNA samples? • What is a Paternity Index? • Can I cheat DNA Paternity testing? • Is it mandatory to get samples from mother? • What is the difference between a blood DNA test and a mouth swab DNA test? • Can hair samples be used for DNA paternity testing? • How old does the child need to be for paternity determination testing? • What if the two possible fathers are related? • What is the best sample to take from a dead body for DNA testing? • Can the presence of blood or semen be dete
DNA Testing largely revolves around sequencing & mapping techniques. The most commonly used method is amplification of DNA by PCR (Polymerase Chain Reaction) & its mapping by RFLP (Restriction fragment length polymorphism) both of which involves analysis of a familial conserved regions of DNA like microsatellites and minisatellites using labelled probes.
