Biology Chapter 10
| Question | Answer |
|---|---|
| the process by which a cell divides into two new daughter cells | cell division |
| first stage ; division of the cell nucleus | mitosis |
| second stage; division of the cytoplasm | cytokinesis |
| one of two identical “sisters” parts of a duplicated chromosome | chromatids |
| area where the chromatids of a chromosomes are attached | centromeres |
| one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope | centrioles |
| period of the cell cycle between cell divisions | interphase |
| series of events that cells go through as they grow and divide | cell cycle |
| first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus | prophase |
| fanlike microtubule structure that helps seperate the chromosomes during mitosis | spindle |
| second phase of mitosis, during which the chromosomes line up across the center of the cell | metaphase |
| the third phase of mitosis, during which | anaphase |
| fourth and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material | telophase |
| one of a family of closely related proteins that regulate the cell cycle in eukaryotic cells | cyclin |
| disorder in which some of the body’s own cells lose the ability to control growth | cancer |
