DNA is an abbreviation for DeoxyriboNucleic Acid. It encodes genetic information necessary for the functioning & development of the organisms. In eukaryotes (humans, animals, & plants), DNA is stored in the nucleus and in some organelles (mitochondria or chloroplasts). While prokaryotes (bacteria) store it in their cytoplasm. This double helix model holds the genetic makeup of every human and can be used to trace their ancestry and ethnicity. While DNA has many benefits, a striking area of importance is its usefulness for profiling or what is known as DNA fingerprinting. DNA Profiling is a molecular technique used to collect genetic information about the individual for parentage testing, criminal and forensic investigations. DNA fingerprinting history began with Sir Alec Jeffrey's discovery of the minisatellite DNA in 1984. Methods Used for DNA Profiling How does DNA profiling work? Our chromosomes contain markers in the DNA sequence that repeat multiple times. The number ...

Every year, thousands of people apply for an immigration visa in India in the hope of reuniting with their families. Especially people who are dependent on their blood relatives living abroad seek to settle with them. Many succeed, while many don’t due to visa rejection. In a case where the consular office may find the primary documents unable to prove the applicant's genetic relationship with his/her sponsor, the visa gets rejected, and the applicant may have to get an Immigration DNA Test before reapplying. Many labs offer DNA testing for immigration purposes; however, a lab/company that provides accredited Immigration DNA test services must be preferred. Process of an Immigration DNA Test Many nations have already adopted it, and many are gradually mandating the provision of relationship-based DNA testing for immigration purposes . An Immigration DNA Test is done in the following steps: 1. The applicant goes to a lab or books an immigration DNA test online. 2. An authorized col...
