A Scientist Developed a Procedure That Would Cause a Particular

A scientist developed a procedure that would cause a particular chemical to bind with the nitrogen base adenine.If this chemical were applied prior to S in the cell cycle,what might be a logical prediction of the outcome?

A) The DNA replication would proceed except that all adenine would have the chemical bound to it and is incorporated into the new sister chromatids.
B) The DNA replication would proceed except that everywhere an adenine was supposed to be,a thymine was substituted into the new developing strand.
C) The DNA replication would proceed except cytosine and guanine would continue to form base pairs.
D) The DNA replication would stop because if adenine were bound then thymine would not have a complement with which to base pair.
