Verified step by step guidance

Understand the cell cycle: The cell cycle is a series of phases that a cell goes through as it grows and divides. It consists of interphase (G1, S, G2) and the mitotic phase (M).

Identify the G1 phase: The G1 phase, or Gap 1 phase, is the first stage of interphase. During this phase, the cell grows in size and synthesizes mRNA and proteins that are required for DNA synthesis.

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

Clarify the role of G1: In the G1 phase, the cell is primarily focused on growth and performing its normal functions. It is not yet replicating its DNA or preparing for mitosis.

Conclude with the correct answer: The G1 phase corresponds to normal growth and cell function, as the cell is actively growing and carrying out its regular activities during this time.
