Question

cells pause through a ( g_2 ) checkpoint before entering mitosis. ideally, if dna damage is detected, the cells do not enter mitosis until the damage is repaired. why is dna damage repaired before cells enter mitosis?
so that the chromosomes can align at the metaphase plate during mitosis
so that the cytoplasm can be divided equally between the two daughter cells
so that another round of dna synthesis does not have to take place
so that healthy daughter cells are produced, allowing the organism to continue growing

which of these must occur during s phase of the cell cycle so that two daughter cells can be produced during m phase?
the chromosomes must be joined.
the cell membrane must be expanded.
the dna must be replicated

Explanation:

For the first question: DNA damage repair ensures healthy daughter cells. Unrepaired DNA could lead to faulty cells, hindering organism growth. Mitosis aims to produce identical, healthy cells.
For the second question: During S - phase (synthesis phase), DNA replication occurs. This provides each daughter cell with a complete set of genetic material during M - phase (mitosis). Without DNA replication in S - phase, daughter cells would lack sufficient genetic information.

Answer:

So that healthy daughter cells are produced, allowing the organism to continue growing.
The DNA must be replicated.
