The chemical structure of everyone's DNA is the same.
The only difference between people (or any animal) is the order of the base pairs
The information contained in DNAis determined primarily by the sequence of letters along the zipper .
Structure of DNA
The different sequence Segments that vary in size and composition and have no apparent function are called minisatellites The different sequences is the same as the word "POST" has a different meaning from "STOP" or "POTS," even though they use the same letters. i
On some human chromosomes, a short sequence of DNA has been repeated a number of times.
The repeat number may vary from one to thirty repeats these repeat regions are usually bounded by specific restriction enzyme sites cut out the segment of the chromosome containing this variable number of tandem repeats ( VNTR's )
Identify the VNTR's for the DNA sequence of the repeat.
