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 STS51 and STS52 to be present in BAC D? 

#SCPH06 I Botany
  1. Yes, STS51 and STS52 should both be present in BAC D
  2. No, STS51 and STS52 should not be present in BAC D, it will be present in BAC B only
  3. Yes, only  STS51 should be present in BAC D
  4. Yes STS51 and STS52 should both be present in BAC B, C, D, E and F
