Which duplication method corresponds to the run & load process?

• A. Mitosis
• B. Manual Duplication
• C. Both
• D. Neither

Answer: (A)

Mitosis is the process that duplicates genetic material and then distributes those copies into two new cells. In the cell cycle, DNA is replicated to create identical sister chromatids, and during mitosis those chromatids are carefully separated so each daughter nucleus gets an identical copy. This fits a run-and-load idea where the genome is run through replication and then loaded into two separate cells, ensuring the outputs are genetically equivalent.

Manual duplication isn’t a natural cellular mechanism, so it doesn’t describe how cells duplicate their own genetic material. The option that implies two different processes isn’t correct because the standard cellular duplication for somatic cells is handled by mitosis, producing two identical daughter cells.
