Paternity DNA testing for twins presents unique challenges that require attention to additional details. Before beginning the DNA testing process on twins who may have different fathers, there are several factors to consider. There are two possible scenarios when the paternity of a set of twins is in question, depending on whether the twins are…Details
In 1993, Kary Mullis received the Nobel Prize for inventing the Polymerase Chain Reaction, also known as PCR. This procedure for making billions of copies of DNA has revolutionized modern biology and has become a standard technique for anyone studying DNA. With PCR, specific DNA sequences from very small amounts of DNA sample can be…Details

A large portion of human DNA does not code for genes (units of DNA that contain instructions for creating proteins). These non-coding regions nevertheless contain much information useful for forensic and other human identification applications. Non-coding regions of DNA contain many of the markers used for identity testing. Short tandem repeats (STRs) are sequences of…Details
