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 |
