DNA Fingerprinting is a method of studying human DNA. It is also called DNA profiling. A DNA test or DNA profiling test has many applications. What started around three decades ago as a one-time DNA analysis for criminal investigation is now available for the common public for many applications. Steps involved in a DNA Profiling Test A DNA Profiling Test starts with the collection of DNA samples of the involved parties. For this, buccal swabs are used. A buccal swab or cheek swab is made of sterile cotton that is rubbed against the cheek walls to collect the epithelial cells. These cells will be later isolated/extracted from the cell for analysis. Then the long-strand DNA is broken down into smaller fragments called Short Tandem Repeats (STRs) using the restriction enzymes. This makes it easier to study. However, the resultant STRs need to be amplified using Polymerase Chain Reaction (PCR). Then capillary electrophoresis separates different sized DNA molecules, and a computer

DNA Profiling or DNA fingerprinting is an advanced technique of studying the body's genetic material -the DNA. It is a notable advancement in the research & development and medical fields. The  DNA profiling test   determines a person’s DNA characteristics. This technique is instrumental in forensics for crime investigations – to assess a suspect’s involvement in a crime. The method also finds its use in testing required for immigration purposes, paternity testing, organ transplantation, and medical research, etc. Apart from humans, DNA Profiling also studies plants and animals – this makes way for a lot of research work in agriculture, zoology, and botany. Jeffrey Glassberg and Alec Jeffreys are the two names who developed and significantly contributed to this study of DNA. DNA Profiling Test accurately and uniquely performs genetic identification. No two people can have the same genetic profile, except for identical twins. At DNA Forensics Laboratory Pvt. Ltd., we provide D
