Question

How is non coding DNA used in STR profiling? (3)

Sammy Universe · Accepted Answer

Satellite DNA: long lengths of short tandem repeats (STRs) differs between diff people 
= unique DNA profiles can be made by comparing the STR location
tandem repeats can be cut out w/ restriction enzymes + separated with gel electrophoresis for comparision
