Question

match the events that occur during interphase to the sub - phase when they occur.
the cell divides. the cell replicates its dna.
the cell completes preparation for division. the cells volume begins to increase.
sub - phase event
g₁ phase
s phase
g₂ phase

Explanation:

• G₁ phase: This is the first gap phase. During this time, the cell grows in size (volume begins to increase) as it prepares for DNA replication. It synthesizes proteins and organelles.
• S phase: The synthesis phase. Here, the cell replicates its DNA. Each chromosome is duplicated, and the cell now has twice the amount of DNA as it did in the G₁ phase.
• G₂ phase: The second gap phase. After DNA replication in the S phase, the cell continues to grow and prepares for cell division. It synthesizes proteins needed for mitosis (such as spindle - forming proteins).

Answer:

• G₁ phase: The cell’s volume begins to increase.
• S phase: The cell replicates its DNA.
• G₂ phase: The cell completes preparation for division.
