Yоu аre in the lаb trying tо synthesize DNA in vitrо. You аre upset because the lab seems to be out of dNTPs (deoxynucleoside triphosphates) but you find a tube of dNMPs (deoxynucleoside monophosphates) in the freezer. You add this to your replication reaction instead of dNTPs. Will your reaction work? Why or why not?
