Description : What is the cell division process directly related to the embryonic growth ?
Last Answer : The embryonic growth depends directly on mitosis. Through this type of cell division, the zygote divides itself giving birth to a series of cells that by mitosis too compose differentiated tissues and organs until the formation of a complete individual.

Description : Multiple checkpoints in the eukaryotic cell cycle ensure that division occurs only after sufficient growth and faithful DNA replication, and only when favorable conditions exist. Of the many proteins involved in ... CDKs) are among the most important. How do CDKs function to control the cell cycle?
Last Answer : CDKs phosphorylate various protein substrates that are required for cell cycle progression. Some of the important substrate proteins that CDKs phosphorylate include condensin proteins, which are essential ... which form a stabilizing network under the nuclear membrane that assembles during mitosis.
