Understand the cell cycle phases: The cell cycle consists of interphase (G1, S, and G2 phases) and the mitotic phase (M phase). Each phase has specific functions and processes.
Focus on the G1 phase: The G1 phase is the first stage of interphase, where the cell grows and carries out normal functions. It is a period of cellular growth and preparation for DNA replication.
Identify key processes in the G1 phase: During the G1 phase, the cell increases in size, synthesizes proteins, and produces organelles. This phase is crucial for preparing the cell for DNA replication in the subsequent S phase.
Differentiate from other phases: Chromosome alignment occurs during metaphase of mitosis, DNA replication occurs in the S phase, and nuclear envelope breakdown occurs during prophase of mitosis.
Conclude with the correct answer: Based on the understanding of the G1 phase, the correct answer is 'Cell growth and protein synthesis,' as these are the primary activities during this phase.
