During which part of the cell cycle does DNA replication occur and why is it important? Select one: a. Cell Cycle Reason Interphase The new chromosome is split from the original in this step. b. Cell Cycle Reason Interphase New genetic information causes the chromosomes to line up in the middle of the cell. c. Cell Cycle Reason Interphase The semiconservative replication process creates a whole new DNA molecule for one of the newly divided cells. d. Cell Cycle Reason Interphase Each chromosome must be replicated before the cells divide in order for each new cell to get a complete set of genetic information.
