Problem 2 Tutorial: The variation of VNTRs

Correct!

The VNTR alleles analyzed in DNA fingerprinting experiments are highly variable from individual to individual. How do the many VNTR alleles at a single locus differ from each other?

A. the number if internal restriction endonuclease cleavage sites for the enzyme HaeIII
B. the number of protein coding genes
C. the number of DNA methylation
D. the number of times a simple DNA sequence is repeated
This is the "Number of Tandem Repeats" in the acronym VNTR.

E. NONE of these
