 With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 

You do each PCR reaction and load each one into a separate well of an agarose gel, and then run the gel.

 

 Why is it that having more repeats leads to a band that is higher in the gel?
