Which statement is correct about the cell cycle driving cleavage?

Correct option is A

The correct answer is It is biphasic with only S phase and M phase.
· In early embryonic cleavage, cell division is rapid and biphasic.
· It skips G1 and G2 phases to save time.
· Only S (DNA synthesis) and M (mitosis) phases alternate.
· This ensures fast increase in cell number without growth.
Information Booster:
· Cleavage converts zygote into multicellular blastula.
· No growth in size occurs; only division.
· Seen in frogs, sea urchins, etc.
· DNA replication and mitosis are tightly coupled.
