Which of the following statements about interphase is false?
a. most cells in adult human bodies are in interphase (including g0)
b. dna is replicated in s phase
c. once a cell enters interphase, it always moves on to m phase again
d. cells grow in g1 and g2
e. cells can stop the cell cycle by going to g0

C. Once a cell enters interphase, it always moves on to M phase again

Explanation:

Interphase is the first stage of cell cycle and is followed by M phase. Interphase includes two growth phases called G1 and G2. The S phase of interphase is marked by DNA replication. The G2 phase of interphase is followed by M phase. However, not all the cells that have entered the interphase ends up in M phase.

A cell can be withdrawn from the cell cycle if the checkpoints are not passed through. Many cells halt the process of cell division for some time or even longer and may or may not resume the process of cell division again. For instance, if replication fork is stalled or there is error in DNA replication, the cell will be withdrawn from cell cycle at the G2 checkpoint.
