What to Focus On
- Cell theory explains the origin of cells from pre-existing cells.
- The cell cycle is the interval between two successive cell divisions.
- The cell cycle has two main phases: interphase and M-phase.
- Interphase is active, not resting.
- G1 is the longest growth phase.
- S phase is the only stage where DNA replication occurs.
- Mitosis produces two identical daughter cells.
- It is equational division because chromosome number remains the same.
- Mitosis occurs in somatic cells.
Common Mistakes to Avoid
Interphase is a resting phase where the cell is inactive.
DNA replicates in G1 phase because the cell grows the most there.
When DNA replicates, chromosome number also doubles.
