$A$ recombinant $DNA$ molecule was created by ligating a gene to a plasmid vector. By mistake,an exonuclease was added to the tube containing the recombinant $DNA$. How does this affect the next step in the experiment,i.e.,bacterial transformation?

(D) The experiment will not be affected because the recombinant $DNA$ molecule is a circular,closed structure with no free ends.
Exonucleases are enzymes that remove nucleotides specifically from the free ends of $DNA$ molecules.
Since the recombinant plasmid $DNA$ lacks free $3'$ or $5'$ ends,it will not act as a substrate for the exonuclease enzyme.
Therefore,the integrity of the recombinant $DNA$ remains intact,and the bacterial transformation process can proceed as planned.
