Question

correctly identify the stage in which each event of the cell cycle occurs. (answers can be used multiple times or not at all) duplication of dna disintegration of nuclear envelope dna condenses to form chromosomes cell grows larger and makes more proteins g1 (growth 1) g2 (growth 2) mitosis cytokinesis synthesis

Explanation:

1. DNA duplication occurs during the synthesis (S) phase of the cell - cycle. This is when the cell replicates its DNA to prepare for cell division.
2. The disintegration of the nuclear envelope happens during mitosis, specifically in the pro - phase. This allows the chromosomes to interact with the cytoplasm and spindle fibers.
3. DNA condenses to form chromosomes during mitosis, also in the pro - phase. Condensing DNA into chromosomes helps in proper segregation during cell division.
4. The cell grows larger and makes more proteins during the G1 (growth 1) phase. This is the first growth phase where the cell increases in size and synthesizes proteins and organelles needed for DNA replication and subsequent cell division.

Answer:

1. duplication of DNA: synthesis
2. disintegration of nuclear envelope: mitosis
3. DNA condenses to form chromosomes: mitosis
4. cell grows larger and makes more proteins: G1 (growth 1)
