Figure 27.2 depicts changes to the amount of DNA present in a recipient cell that is engaged in conjugation with an Hfr cell. Hfr-cell DNA begins entering the recipient cell at Time A. Assume that reciprocal crossing-over occurs (i.e., a fragment of the recipient's chromosome is exchanged for a homologous fragment from the Hfr cell's DNA). Use Figure 27.2 to answer the following questions.

-How is the recipient cell different at Time D than it was at Time A?
A)It has a greater number of genes.
B)It has a greater mass of DNA.
C)It has a different sequence of base pairs.
D)It contains bacteriophage DNA.
E)It has a greater number of introns.
