Reproduction of Cell
Chapter 3
| Question | Answer |
|---|---|
| DNA | the material found in a cell's nucleus, that determines the genetic traits of the organism |
| Chromosome | an organized structure that is made up of proteins and DNA |
| Chromatids | One of the two sides replicated by a chromosome during mitosis |
| Cell Cycle | the normal sequence of development and division of a cell |
| Mitosis | the part of the cell cycle during which a cell is NOT dividing. |
| Interphase | the part of the cell cycle during which a cell is not dividing |
| Double Helix | the structure created when the double-stranded molecules of DNA and RNA form |
| Cytokinesis | the division of the parent cell's cytoplasm; |
| Centromere | found in the middle of the chromosome; cell can't divide properly without it |
| Binary Fission | DNA is replicated, then the two different DNA split apart, breaking the cell in two |
| Regeneration | the process of growing new tissue at a wounded site on the organism |
| Asexual Reproduction | method of reproduction where genetically identical offspring come from one parent |
| Sexual Reproduction | method of reproduction where genetically identical offspring come from more than one parent |
| Prophase | first stage of cell division, chromosomes thicken, nuclear membrane disappears. |
| Metaphase | second stage of cell divison; chromosome meet at the middle of the cell |
| Anaphase | third stage of cell divison; chromosomes start to separate |
| Telophase | fourth stage of cell divison; chromosomes reach opposite ends, new nuclear membrane appears, chromosomes uncoil; generally followed by cytokinesis immediatly |
| Centrioles | Functions the organization of the mitotic spindle |
| Budding | Asexual production of new organisms |
