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:
 
How would you use the sequence information presented in to design two new STSs (with new PCR primer pairs) to replace STS5? (Call the new ones STS51 and STS52. STS51 should be present (+) in BAC B, and STS52 should be present (+) in BAC F.)

#SCPH01 Biochemistry
  1. Primers that include the homologous sequence in STS51 and STS52. These primers should specifically amplify only STS52  not  STS51.
  2. Primers that include the non-homologous sequence in STS51 and STS52. These primers should specifically amplify both simultaneously  STS51 and  STS52.
  3. Primers that include the homologous sequence in STS51 and STS52. These primers should specifically amplify only STS51  not  STS52.
  4. Primers that include the non-homologous sequence in STS51 and STS52. These primers should specifically amplify either STS51 or STS52.

As you study two closely related predatory insect species, the two-spot and the three-spot avenger beetles, you notice that each species seeks prey at dawn in areas without the other species. However, where their ranges overlap the two-spot avenger beetle hunts at night and the three-spot hunts in the morning. When you bring them into the laboratory, their offspring behave in the same manner. You have discovered an example of
