Question: 1 / 400

What phase of the cell cycle is characterized by cell growth, repair, and basic functions?

G1 phase

S phase

G2 phase

Interphase

The phase of the cell cycle characterized by cell growth, repair, and basic functions is interphase. Interphase is the time when the cell prepares for division and encompasses three subphases: G1, S, and G2.

In the G1 phase, the cell undergoes significant growth, synthesizes various proteins, and completes everyday functions, laying the groundwork for DNA replication that occurs in the S phase. The S phase is where DNA replication happens, leading to the duplication of chromosomes. Finally, in the G2 phase, the cell continues to grow and prepares for mitosis, ensuring all necessary components are in place for successful division.

Thus, interphase is the correct answer because it collectively involves growth and repair activities across its subphases.
