multicellular organisms, nondividing cells stay in G0 phase. For the cell, why is it better to be held in G₁ rather than S, G₂ or M phase? A. G₁ cells are larger and more likely to perform the normal functions of the cell. B. G₁ cells have not replicated their DNA in preparation for division. C. G₁ cells are the only ones that do not have their chromatin in a highly condensed state. D. MPF is required

Question
In multicellular organisms, nondividing cells stay in G0 phase. For the cell, why is it better to be held in G₁ rather than S, G₂ or M phase?
A. G₁ cells are larger and more likely to perform the normal functions of the cell.
B. G₁ cells have not replicated their DNA in preparation for division.
C. G₁ cells are the only ones that do not have their chromatin in a highly condensed state.
D. MPF is required to enter S phase, so the cell is committed to entering M phase if the cycle moves beyond G₁.
How many does the chromosome number of the species
A. Is equal to the diploid chromosome number.
B. Refers to the chromosome number of the somatic cell.
C. Is a constant number for the organisms of the species generation after generations.
D. All of the above.
Which statement about the daughter cells following mitosis and cytokinesis is correct?
A. They are genetically different from each other and from the parent cell.
B. They are genetically identical with each other and with the parent cell.
C. They are genetically identical with each other but different from the parent cell.
D. Only one of the two daughter cells is genetically identical with the parent cell.
