Cyanogenic Glycosides and Glucosinolates are nitrogen containing secondary metabolites in plants. Following are some statements regarding the action of Cyanogenic Glycosides and Glucosinolates;

a) Cyanogenic Glycosides release the poison hydrogen cyanide by the action of enzyme known as Hydroxynitrile lyase

b) Release of the mustard-smelling volatiles from glucosinolates is catalyzed by a hydrolytic enzyme, called a thioglucosidase or myrosinase

c) substerate for Glycosidase is Cyanogenic glycoside and Thioglucosidase is Aglycone

d) Like cyanogenic glycosides, glucosinolates are stored in the intact plant separately from the enzymes that hydrolyze them, and they are brought into contact with these enzymes only when the plant is crushed

You obtain 6 BACs (of known order, as shown below) and 7 STSs (of unknown order) that derive from a region of mouse chromosome 16 whose genomic sequence has not yet been finished.   

 

By PCR (using 20-bp primers at either end of each STS), you test each of the 6 BACs for the presence (+) or absence (-) of each of the 7 STSs. You obtain the following results:

 

Would you expect the DNA sequence of PCR product obtained at STS5 using mouse genomic DNA as template to more closely resemble that obtained using BAC B, BAC D, or BAC F? Briefly explain your answer.
