Cell Cycle and Mitosis
| Question | Answer |
|---|---|
| the life cycle of a cell | cell cycle |
| cell spends most of its life in this stage of the cell cycle | interphase |
| the two parts of the cell cycle | interphase and cell division |
| the three parts of interphase | G1, S, and G2 |
| what happens during interphase | growth and DNA replication |
| the cell grows in size and increases in number of organelles during which part of interphase? | G1 |
| the cell produces proteins necessary for cell division during which part of interphase | G2 |
| DNA is replicated during which part of interphase? | S |
| supercoiled DNA and protein | chromosome |
| one half of a replicated chromosome | chromatid |
| the point of attachment between two sister chromatids | centromere |
| uncoiled DNA and protein | chromatin |
| a replicated chromosome is made of two | chromatids |
| cell division consists of these two stages: | M Phase and Cytokinesis |
| what are the two types of M Phase | mitosis and meiosis |
| what happens during the M Phase? | division of the nucleus |
| what happens during cytokinesis | division of the cytoplasm |
| what are the four stages of mitosis | prophase, metaphase, anaphase, telophase |
| when does the chromatin condense to form chromosomes? | prophase |
| when do the chromosomes line up at the equator of the cell? | metaphase |
| when do the sister chromatids divide and begin moving apart? | anaphase |
| when do the chromosomes reach opposite ends of a cell? | telophase |
| when does the nucleus and nuclear membrane begin to disassemble? | prophase |
| when does the nucleus and nuclear membrane begin to reassemble? | telophase |
| what stage follows telophase? | cytokinesis |
| what stage follows S phase | G2 |
| What stage follows anaphase | telophase |
| what stage follows G2 | M phase or Prophase in Mitosis |
| what stage precedes anaphase? | metaphase |
| this nuclear division process results in two cells identical to each other and to the original cell | mitosis |
| this nuclear division process results in four cells having exactly half of the DNA of the original cell | meiosis |
| this nuclear division process occurs in body cells such as muscle and skin | mitosis |
| this nuclear division process occurs in reproductive cells such as sperm and egg | meiosis |
