Mitosis and miosis
| Question | Answer |
|---|---|
| anaphase | the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle. |
| asexual reproduction | is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes and almost never changes the number of chromosomes. |
| cell cycle | The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. |
| centromere | the point on a chromosome by which it is attached to a spindle fiber during cell division. |
| chromosome | a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes. |
| crossing over | the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring. |
| cytokinesis | the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells. |
| interphase | the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis. |
| metaphase | the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers. |
| mitosis | a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. |
| prophase | the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division. |
| sexual reproduction | the production of new living organisms by combining genetic information from two individuals of different types of gender |
| telophase | the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed. |
