Cell Cycle
Cell Cycle and Mitosis
Question | Answer |
---|---|
chromatin | long strands of DNA, resembles spaghetti |
mitosis | cell division of all body cells (asexual reproduction) |
cytokinesis | division of the cytoplasm, occurs after telophase |
chromosomes | condensed DNA, resembles an X |
sister chromatids | two identical pieces of DNA that make up a chromosome |
centromere | the part of a chromosome that holds the sister chromatids together |
3 phases of Interphase | G1, S, G2 |
First phase of Interphase | G1 |
What occurs in G1 of Interphase? | growth of the cell, 1st part of Interphase |
What occurs in S phase of Interphase? | DNA replication (make a copy of the DNA for the new cell being made) |
What occurs in the G2 phase of Interphase? | growth of cell, 3rd part of Interphase |
What phase of the cell cycle does the cell spend most of its life? | Interphase (G1, S, G2) |
What part of the cell cycle does DNA replicate? | During S phase of Interphase |
What are the 4 stages of Mitosis? | Prophase, Metaphase, Anaphase, Telophase |
What is the first stage of Mitosis? | Prophase |
What is the second stage of Mitosis? | Metaphase |
What is the third stage of Mitosis? | Anaphase |
What is the fourth stage of Mitosis? | Telophase |
What 3 things happen to the cell during Prophase? | the chromatin turns into chromosomes, nucleus begins to disappear, centrioles start to move to the poles |
What happens to the cell during Metaphase? | chromosomes move to the MIDDLE of the cell |
What happens to the cell during Anaphase? | Chromosomes move AWAY/APART from the middle of the cell and go toward opposite ends of the cell. |
What happens to the cell during Telophase? | Form two new cells, chromosomes change back into chromatin |
When do the chromosomes line up in the middle of the cell? | Metaphase |
When do the chromosomes move apart? | Anaphase |
When do the new cells form? | Telophase |
What is the process called that divides the CYTOplasm? | CYTOkinesis |
What are the 4 MAIN parts of the entire CELL CYCLE? | G1, S, G2, M (MITOSIS) |
What biomolecule is DNA? | nucleic acids |
