Answer:
Unzipping, Complementary base pairing, Backbone formation.
Also known as Initiation, Replication and Termination.
1. Interphase: replication and growth of the chromosomes occur.
2. Prophase: the chromatin condenses to see the individual chromosomes and centrioles move toward the opposite poles of the cell and spindle fibers grow.
3. Metaphase: the chromosomes align in the center of the cell.
4. Anaphase: spindles attach to the chromosomes and split them in part towards the opposite poles.
5. Telophase: the cell begins to separate into to new daughter cells.
6. Cytokinesis: the nucleus begins to form and the cells are completely cut off from each other.
