Interphase includes the G1, S, and G2 phases. 2. Mitosis is the phase where cell division occurs. 3. Chromosome condensation is completed during prophase.
Mitosis consists of three stages: prophase, metaphase, and telophase. 2. The G2 phase is primarily for DNA replication. 3. Cells in the G0 phase are actively dividing.
The S phase is when organelle duplication occurs. 2. Metaphase is marked by the presence of the nuclear envelope. 3. The G1 phase involves normal metabolic activities.
Mitosis is only seen in haploid cells in plants. 2. G1 phase is the period of cell growth. 3. During metaphase, chromosomes can be clearly observed under the microscope.
