Replication of the bacterial is required before the bacterial cell can be duplicated.

Inside the nucleus, the two strands of nucleic acids that exist in the form of a double helix make up the molecule called .

During which phase do chromosomes first become visible?

In mitosis, three major check points are built into the cell cycle. These checkpoints make sure that certain criteria are met before proceeding to the next step. Explain the major responsibilities of the checkpoints between the following steps: between G1 to S, between G2 to mitosis, and between metaphase to anaphase.

Which phase of mitosis involves the shortening of the microtubules as the chromosomes move toward the poles?
