I am going to try to explain in simple terms what VNTR's are and how I used them in my research. 

Every living cell contains DNA.  Only about 1 percent of DNA in humans encodes for mRNA (the precursor for proteins and other signaling molecules).  The remaining 99 percent is called "junk" DNA.  This junk has areas that contain repeated patterns.  For instance, the four building blocks of DNA (Guanine, Cytosine, Adenosine, and Thymine) may repeated with this motif: TAAGCCTA.  The number of times that this pattern repeats can vary in different individuals.  For instance, in one person, they may have ten repeats while someone else may have only seven.   

Variable Number Tandum Repeats (VNTR's) are used in cases of paternity testing, crime scene/suspect linking, and even body identification.  The number of repeats are inherited from a persons parents.  You can test several people to find out if they are the parents. 

Lets look at some examples.
