Final answer:
Interfering with the metabolism of the reproductive cycle of tumor cells slows down the growth of the tumor cells.
Step-by-step explanation:
The effect of interfering with the metabolism of the reproductive cycle of tumor cells is that it slows down the growth of the tumor cells. By damaging the DNA of the cancer cells and inhibiting the synthesis of new DNA strands, the cell division and replication of the tumor cells can be stopped, ultimately halting the progression of the cancer. This can be achieved through chemotherapy drugs that interfere with cell division and mitosis, or by targeting specific processes that are essential for tumor cell growth.
