Answer:
The correct answer is "Is there a pattern to the movement of homologous chromosomes in the presence of this compound?"
Explanation:
A compound that prevents the separation of the homologous chromosomes in anaphase I is of great interest since it will cause cell cycle arrest, an effect that is looked in anti-cancer drugs. However, a throughout study of the compound must be done before it could be used for clinical trials. One of the questions that could be answered in this study is: "Is there a pattern to the movement of homologous chromosomes in the presence of this compound?". The answer of this question will let us know if the cells will go to apoptosis, which is what we look for in an anti-cancer drug.
