Cells will usually divide if they receive the proper signal at a checkpoint in the G1 phase of the cell cycle. In mammalian cells , this checkpoint is called the restriction point. The G1 phase is a phase of the cell cycle that takes place in eukaryotic cell division. In this phase the cell synthesizes mRNA and proteins in preparation for the subsequent steps leading to mitosis. It ends when the cell moves into the S phase of interphase.

Answer:
They contain different genetic material.
Explanation:
DNA viruses contain DNA for genetic material while RNA viruses contain RNA.   When RNA viruses enter a host cell, they must convert their RNA into DNA. DNA viruses change the biochemical functions in the nucleus for DNA replication and creates RNA that controls the proteins needed by the DNA virus (capsid).
