Question

the cell cycle is
____________________
during the cell cycle, a cell
____________________
interphase is ____________________
interphase is divided into three phases: __ & __
g₁ phase
the g₁ phase is a period of activity in which cells ____________________
__________________ cells will ________________ and synthesize new __________________
____________________
s phase
the s phase replicates __________________ and synthesizes __________________ molecules.
when dna replication is completed, ____________________
____________________
g₂ phase
during the g₂ phase, many of the organelles and molecules required for ____________________
____________________
when g₂ is completed, the cell is ready to enter the ____________________

1. during what stage does the g1, s, and g2 phases happen?
2. during what phase of the cell cycle is dna replicated?
3. during what phase of the cell cycle does the cell grow?
4. put the following stages of the cell cycle in order: g2, s, g1, m.
5. put the following actions in order: dna replication, cell grows, cell division, cell prepares for mitosis.

Explanation:

1. The G1, S, and G2 phases occur during interphase. Interphase is the stage where the cell prepares for division.
2. DNA replication occurs during the S (synthesis) phase. This is when the cell duplicates its genetic material.
3. The cell grows during the G1 (gap 1) phase. In this phase, the cell increases in size and synthesizes new proteins and organelles.
4. The correct order of the cell cycle stages is G1, S, G2, M. G1 is the first growth phase, S is for DNA synthesis, G2 is the second growth phase (preparation for mitosis), and M is the mitosis (cell division) phase.
5. The correct order of the actions is: cell grows (G1), DNA replication (S), cell prepares for mitosis (G2), cell division (M). This follows the sequence of the cell cycle phases.

Answer:

1. Interphase
2. S phase
3. G1 phase
4. G1, S, G2, M
5. Cell grows, DNA replication, cell prepares for mitosis, cell division
