A repeating sequence of cellular growth and division during the life of a cell
Cell cycle
Cell Cycle
A repeating sequence of cellular growth and division during the life of a cell
Interphase
Phase where the cell prepares for division and is not dividing
Phase where the cell prepares for division and is not dividing
Interphase
Cell Division
Made up of mitosis and cytokinesis
Made up of mitosis and cytokinesis
Cell division
Mitosis
The process of dividing the nucleus in two daughter nuclei
The process of dividing the nucleus in two daughter nuclei
Mitosis
Cytokinesis
The process of separating the organelles and cytoplasm
The process of separating the organelles and cytoplasm
Cytokinesis
G1
The cell grows rapidly as the cell builds more organelles - takes up most of the cells life - the first gap phase
The cell grows rapidly as the cell builds more organelles - takes up most of the cells life - the first gap phase
G1
S
Where the cells DNA is copied - the synthesis phase
Where the cells DNA is copied - the synthesis phase
S
G2
Where the cell continues to grow and prepares to divide - micro tubes are formed - the second gap phase
Where the cell continues to grow and prepares to divide - micro tubes are formed - the second gap phase
G2
Microtubules
Made of protein fibers and will help with division - formed in the G2
Made of protein fibers and will help with division - formed in the G2
Microtubules
The phases of mitosis
Prophase
Metaphase
Anaphase
Telophase
Prophase
- chromosomes condense
- nuclear membrane breaks down
- the spindle forms
- centrosomes and centrioles appear
- chromosomes condense
- nuclear membrane breaks down
- the spindle forms
- centrosomes and centrioles appear
Prophase
Metaphase
- chromosomes are condensed
- nuclear membrane dissolves
- chromosomes line up along the equator
- spindle fibers link between the centromere of each chromosome and the poles
- chromosomes are condensed
- nuclear membrane dissolves
- chromosomes line up along the equator
- spindle fibers link between the centromere of each chromosome and the poles
Metaphase
Anaphase
- spindle fibers shorten
- chromatids move toward opposite poles and the spindle fibers shorten
