DNA and paternity testing: How does DNA testing work?

How does DNA testing work?

It works by detecting certain parts, or “markers” in the DNA molecule that are known to vary greatly between unrelated people. Tests compare the DNA at a number of these markers to determine if people are related.

 

The process is called Short Tandem Repeat (STR) profiling. STR profiling is a very sensitive DNA testing procedure that was originally developed for forensic analysis. DNA is extracted from the sample and a special enzyme is used to copy the genetic code at the relevant regions in the DNA. An STR profile is the result of several separate DNA tests.
