Mitosis Flashcards
What is Mitosis?
The Cell Cycle that splits a cell in two to create two identical daughter cells
What are the two phases of the Cell Cycle called?
- Interphase
- Mitotic Phase
What is the Interphase and it’s three phases?
The Interphase refers to the first phase of the Cell Cycle, which increases causes the Cell to grow in size and prepares for DNA replication
- G1 Phase: The Cell grows larger in size and synthesizes protein, whilst maintaining normal function
- S Phase: DNA Replication occurs
- G2 Phase: The Cell continues to grow and synthesizes proteins necessary for Division
What is the Mitotic Phase?
A multi step process that works toward aligning duplicated chromosomes, separating them, and eventually splitting up the cell to two new daughter cells
What are all the phases of the Mitotic Phase?

- Prophase: Cell prepares to divide, where chromosomes are made visible and condensed in the middle
- Prometaphase: Occurs between Prophase and Metaphase, the nuclear envelope breaks down and chromosomes begin to align themselves
- Metaphase: Chromosomes align themselves in the middle
- Anaphase: Cell elongates as sister chromatids begin splitting apart
- Telophase: Final phase of Mitosis where the first three stages of Mitotic Phase are reversed
What is Cytokinesis?
The second part of the Mitotic Phase where the physical separation of a Cell occurs to create two daughter Cells
What of the genes that may incur a mutation resulting in cancer?
Proto-oncogenes and Tumor suppressor gene
