What would be the expected result of a drug that affected a particular tissue by causing new DNA to form with covalent bonds instead of hydrogen bonds?
A)None of the cells in the affected tissue would be able to leave G0 and enter the cell cycle.
B)Replication of DNA would result in identical DNA strands instead of complementary strands.
C)Mitosis of cells in the tissue would result in the production of three new daughter cells instead of just two.
D)The new cells that formed within this tissue would not be able to complete the next round of mitosis successfully.

If, during S phase of one cell cycle, the replicated DNA had covalent bonds rather than hydrogen bonds, the cell could complete that round of cell division, resulting in two new daughter cells. When either of these two new daughter cells then reentered the cell cycle, it could not complete the cycle. The tight covalent bonds of the DNA in each of these cells would not break apart to allow each strand to separate and be used as templates for DNA replication and synthesis. Thus, the cycle would be arrested at this stage.
