Explain the importance of gene regulation in prokaryotic cells.
-Explain the importance of gene regulation in eukaryotic cells.
Answer:
Prokaryotic cells can only regulate gene expression by controlling the amount of transcription. As eukaryotic cells evolved, the complexity of the control of gene expression increased. For example, with the evolution of eukaryotic cells came compartmentalization of important cellular components and cellular processes.

How quickly can mitosis occur in a paramecium?
Answer:
Under favourable conditions, Paramecium multiplies rapidly up to three times a day. Binary fission divides a cell transversely and followed by mitotic division in the micronucleus. Macronucleus divides amitotically. The gullet also divides into two halves
Explanation:
HOPE IT HELP
Paramecium can be multiplied rapidly up to three times a day.
In paramecium binary fission divides a cell transversely in two parts .Then after it followed by mitotic division in the micronucleus if paramecium.However Macronucleus divides amitotically in life.statement does not describe cell cycle checkpoints?
Answer:
Defective checkpoints results in death of the cell.
Normal checkpoints make sure the cell has enough resources for cell division. Normal checkpoints ensure the cells commits apoptosis if the cell has a problem it cannot fix itself.
