can you please answer this question?

You were given two dishes of mammalian cell culture. One dish had been treated
with drug A, and another with drug B. You found that cells treated with drug A
were all in M phase, whereas cells treated with drug B were in G1 phase. Please
list at least two possible targets for each drug and briefly describe why these
drugs can cause cell cycle arrest.

[sweetsunil21]

for drug stopping cells in m phase the target lies in spindle apparatus(u can find many)
for drug stopping cells in phase the target is in dna replication enzymes.

hope its correct!!
