The Anaphase Promoting Complex (APC) targets specific proteins for degradation during mitosis. A mutation in the gene encoding APC would most likely result in which of the following?
Premature entry into anaphase

A researcher is studying mitosis in a novel diploid organism with 2n = 16 chromosomes. During metaphase, a drug is applied that inhibits the separation of sister chromatids but allows the cell to progress through anaphase and telophase. At the end of this aberrant cell division, what is the most likely chromosomal composition of the resulting daughter cells?
Two diploid cells (2n=16) each
One diploid cell (2n=16) and one cell with no chromosomes
One tetraploid cell (4n=32)
Two cells with 8 chromosomes each
