joja [24]

Answer:

Groups 4 to 7 are most likely to be undergoing the mitotic phase of the cell cycle.

Explanation:

Since the four proteins used p16,  p18,  p21, and  p27 are inhibitors of cyclin-dependent kinases (CDK), their absence indicates that the cell is undergoing mitosis - the cell cycle is regulated by CDKs. In the absence of these inhibitors, the cell cycle moves on forward. Because the bar for DNA replication is longer in the case for groups 4 to 7, it is indicative of the fact that these cells have gone through the mitotic phase.

Hope that answers the question, have a great day!

These organisms with common characteristics are believed to be closer to one another and evolved from the same ancestors.

In the above question, as there is only one difference between the cytochrome c of humans and rhesus, hence rhesus is the closest to humans. Pigeons has lesser number of differences than fruit fly, hence it is second on the list. Fruit fly has the maximum differences hence it is placed last.
