Chromosome duplication occurs for the beginning of which process? select all that apply.

Vladimir [108]

The image shows the process of mitosis. The replication of DNA happens at prophase of the mitosis process. This results in the duplication of the chromosomes This is followed by the segregation and division of the duplicated chromosomes into the two daughter cells.
