During which phase of interphase does the cell grow and perform its normal functions?

During which phase of interphase does the cell grow and perform its normal functions?

• A. Stage of interphase in which DNA is replicated.
• B. Phase where spindle forms.
• C. Stage of interphase in which cell grows and performs normal functions.
• D. The period of cell division.

Answer: (C)

During interphase, growth and normal cellular activities occur in the first subphase, when the cell increases in size, manufactures proteins, and carries out routine metabolism to prepare for DNA replication. DNA duplication happens in the next subphase, while another growth and preparation period occurs before mitosis. Spindle formation and cell division happen later, during mitosis, not during interphase. So the phase where the cell grows and performs its normal functions is the growth phase before DNA replication.
