You Are Carrying Out Experiments in Cell Fusion by Fusing

question 81

Multiple Choice

You are carrying out experiments in cell fusion by fusing together cells at different stages of the cell cycle. You then observe the behavior of each nucleus residing in the combined cytoplasm of the two cells. Which of the following responses would occur if you fused an S-phase cell to a cell in the M phase?

• A)The nucleus from the M phase cell would start to replicate its DNA.
• B)The S-phase nucleus would undergo premature chromosomal condensation to form a set of elongated compacted chromosomes.
• C)The M phase nucleus would be affected in such a way that its compacted chromosomes decondense.
• D)The chromatin in the S-phase nuclei would be compacted, but pulverized chromosomal fragments would form.
• E)The S-phase nucleus would undergo premature chromosomal condensation; the compacted chromosomes would be visibly doubled.
