Question

which of the following is a signal that a cell is ready to enter synthesis phase? cell recognition of dna overload the nucleus begins to split dna replication occurs

Explanation:

In the cell - cycle, the synthesis (S) phase is when DNA replication occurs. A cell is ready to enter the S - phase when it has grown and has the necessary components for DNA replication. DNA replication does not signal readiness to enter S - phase but is the main event of S - phase. Nucleus splitting occurs during mitosis, not as a signal for S - phase. Cell recognition of DNA overload is not a signal for entering S - phase.

Answer:

None of the above options are correct signals that a cell is ready to enter synthesis phase.
