Question

cell cycle
label the cell cycle
cell growth
cell division
dna replication
preparation for mitosis
cell division

Explanation:

Identify the main phases of the cell cycle

• The outer green sector represents "Cell growth", which corresponds to the G1 Phase.
• The yellow sector represents "DNA replication", which corresponds to the S Phase.
• The light blue sector represents "Preparation for mitosis", which corresponds to the G2 Phase.
• The large purple bracket grouping G1, S, and G2 phases represents Interphase.

Identify the division phases

• The inner grey arrow labeled "Cell division" represents the overall division process, which is divided into Mitosis (the main division of the nucleus) and Cytokinesis (the division of the cytoplasm).
• The purple bracket grouping the four sub-phases of nuclear division represents Mitosis.
• The final red box at the end of the division sequence represents Cytokinesis.

Identify the sub-phases of mitosis

• The four sequential sub-phases of mitosis within the bracket are:

1. First sub-phase: Prophase
2. Second sub-phase: Metaphase
3. Third sub-phase: Anaphase
4. Fourth sub-phase: Telophase

Answer:

Based on the cell cycle diagram, the correct labels for each blank box (from top to bottom, outer to inner) are:

• Cell growth (Green sector): G1 Phase
• DNA replication (Yellow sector): S Phase
• Preparation for mitosis (Blue sector): G2 Phase
• Large bracket grouping G1, S, and G2: Interphase
• Large bracket grouping the four division stages: Mitosis
• Four sequential division stages (top to bottom):

1. Prophase
2. Metaphase
3. Anaphase
4. Telophase

• Final division stage (Red box at the end of the arrow): Cytokinesis
