You Are in the Lab Trying to Synthesize DNA in Vitro

question 17

Multiple Choice

You are in the lab trying to synthesize DNA in vitro. You are 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?

• A) No, cleavage of dNTP drives the formation of the covalent bond between the nucleoside monophosphate and the growing DNA strand.
• B) Yes, only the nucleoside monophosphate ultimately is incorporated into the growing DNA strand.
• C) No, all three phosphates on the nucleoside triphosphate are incorporated into the growing DNA strand.
• D) Yes, the formation of the covalent bond between the nucleoside monophosphate and the growing DNA strand is energetically favorable.
