Verified step by step guidance

Understand the cell cycle: The cell cycle consists of several phases, including G1, S, G2, and M phases. Each phase has distinct roles in cell growth and division.

Identify the G1 phase: The G1 phase is the first stage of interphase, which is the period between cell divisions.

Recognize the activities in the G1 phase: During the G1 phase, the cell grows in size and synthesizes proteins and organelles. It is a period of cellular activity and growth.

Differentiate from other phases: The S phase is where DNA replication occurs, the G2 phase is where the cell prepares for mitosis, and the M phase includes mitosis and cytokinesis.

Conclude the description: The G1 phase is best described as the phase where the cell grows and carries out normal functions, distinguishing it from DNA replication, mitosis preparation, and cytokinesis.
