DNA testing or genetic counseling is a scientific process by which DNA of an individual is analysed to determine the relationships between an individual and relatives. DNA testing can be performed on the various strands of DNA and compared to determine the relations between an individual and relatives. DNA testing labs in Delhi NCR are some of the prominent DNA testing laboratories located in India.
DNA testing can be used to trace relationships between an individual and his ancestors, or to find out about his history. DNA testing can also help in detecting any kind of abnormality in the DNA structure of an individual. DNA testing has proved very helpful in forensic studies. DNA testing helps in proving relationships between a person and his ancestors. Similarly DNA testing can also prove relationships among individuals who have come from different parts of the world by analyzing DNA samples.
DNA testing is becoming an essential part of DNA analysis used for DNA fingerprinting and ancestry testing. DNA is a molecule of DNA composed of ‘protein’ building blocks called’ RNA and DNA base’, which is very similar to the DNA of living organisms. DNA is very fragile and needs great care during storage. DNA storage methods need to be very carefully done to maintain its strength and integrity over long period of time. DNA testing laboratories in Delhi are a hub for DNA testing.
DNA testing is divided into two forms, namely DNA testing and DNA typing. Genetic testing can be performed on many DNA samples stored in various DNA banks. The DNA banks contain DNA samples of people from all over the world who are members of various ethnic groups and also from different geographical regions. DNA testing on samples stored at DNA banks can be used to reveal the true identity of the DNA donors and conclusively identify the DNA sample. DNA testing using DNA samples stored at home or other DNA testing laboratories in Delhi can also reveal the true identity of DNA donors and helps in forensic research. DNA typing on the other hand is used to detect and profile DNA donors and can also be useful in legal proceedings.
DNA testing is now an integral part of DNA analysis used in forensic DNA analysis for both DNA fingerprinting and DNA ancestry tests. DNA testing of sample taken from saliva of DNA donors helps in DNA profiling that again helps in DNA fingerprinting. DNA testing has recently become a part of DNA evidence and the courts have started relying on Genetic testing in criminal cases. DNA testing of crime scene samples has helped in proving innocence of suspects. DNA testing has even helped in setting aside cases like rape, murder and sexual abuse etc.
