Mitosis and the Cell Cycle
New cells are formed from existing cells.

The cells that give rise to new cells are called _________________ cells.

The new cells are the _________________ cells formed when the parent cell divides.
The cell cycle describes the process. Nuclear division, or ________________ takes only a small
fraction of the cell cycle. During the rest of the cycle, __________________ information is
_______________.
Interphase
During interphase, the genetic material in the ______________ appears as ________________.
During the first part of interphase the cell ______________ and the ________________ are
replicated. Then, DNA is __________________. Each length of DNA forms a ________________
of strands. These strands are ______________________ and are called sister
_____________________. They are joined together at the ________________________.
Mitosis
In mitosis a cell inherits ___________ sets of chromosomes. This means the parent cell and the
daughter cells are _____________. The symbol _____ represents this state, where n = the
number in a set of chromosomes.
Mitosis increases cell numbers in an organism. Growth and ____________ depends on mitosis,
as does _____________ reproduction in plants and animals.
Stages of Mitosis
Prophase
1. The nucleolus begins to fade.
2. The _______________________ duplicate and move to opposite poles
3. The centrioles form ________________ fibres.
4. Chromosomes ________________ and thicken, becoming visible.
5. The ________________ envelope begins to disintegrate
Metaphase
1. Chromosomes line up along the ________________ of the cell.
2. One chromatid of each pair lies on either side.
3. Spindle fibres attach to the __________________-.
Anaphase
1. The spindle fibres begin to _______________.
2. Sister chromatids are pulled apart and move to opposite ____________ of the cell.
Telophase
1. Separation of chromatids is complete.
2. Spindle fibres disintegrate
3. Each chromatid is now a ____________________
4. The nuclear ___________________ reforms around each group of chromosomes.
5. The cell divides along the waist via ________________________.
