DNA Profiling 
 
Answer	Marks 
 
1. 
a) 
i)	Highly repetitive sequences of DNA bases 
 
ii)	VNTRs differ in size/length between different individuals 
-VNTRs occur in lots of different places in the genome between different individuals 
-	The difference in size and location of VNTRs creates a genetic fingerprint unique to the individual which can be used to identify them. 
 
b) 
i)- PCR amplifies DNA 
-	It copies the areas that contain VNTRs using primers 
-	The result is a sample containing man...
