I can describe the phases of the cell cycle including mitosis.
The cell cycle and cell division: mitosis
I can describe the phases of the cell cycle including mitosis.
Lesson details
Key learning points
- Most cells in multicellular organisms go through different phases that are part of a cell cycle.
- The main phases of the cell cycle are interphase and mitosis.
- During cell interphase, each chromosome is copied, sub-cellular structures are copied.
- During mitosis, chromosome copies line up along the middle of the cell and the nucleus divides.
- After division, the two new cells both have a copy of the same chromosomes.
Keywords
Cell cycle - The process by which cells divide; this involves a specific set of phases.
Mitosis - A type of cell division that produces genetically identical cells.
Nucleus - A sub-cellular structure that contains the genetic material (DNA); controls the cell activities.
Chromosomes - Tightly coiled strands of DNA that carry the genetic material.
Common misconception
Chromosomes are halved when the cell splits.
Slides repeatedly address the concept that chromosomes are copied.
