You are conducting a genetic screen using Caenorhabditis elegans embryos to isolate mutations affecting anaphase A. Therefore, you need to look for embryos in which
A) the centromeres do not move toward the poles.
B) the poles do not move apart.
C) the spindle apparatus does not disassemble.
D) sister chromatids fail to separate.
