SC.912.L.16.14 Describe the cell cycle, including the process of mitosis. Explain the role of mitosis in the formation of new cells
and its importance in maintaining chromosome number during asexual reproduction.
SC.912.L.16.3 Describe the basic process of DNA replication and how it relates to the transmission and conservation of the
genetic information.
