Term | Definition |
---|---|
anaphase | stage of meiotie or mitotie cell division in which the chromosomes move away from one to another to opposite poles of the spindle |
asexual reproduction | type of reproduction by which offspring arise from a single organism does not involve the fusion of gametes and almost never changes the number of chromosomes |
cell cycle | series of events that lead to division and duplication of its DNA |
cell division | process which a parent cell divides into 2 or more daughter cells |
centromere | part of chromosome that links sister chromatids or a dyad |
chromosome | thread-like structures located inside the nucleus of cells |
crossing over | exchange of genetic material between homologous chromosomes that results in recombinant chromosomes |
cytokinesis | physical process of cell division |
interphase | phase of cell cycle which a typical cell spends most of its life |
metaphase | second phase of mitosis, process that separates duplicated genetic material |
mitosis | nuclear division plus cytokinesis produces two identical daughter cells during prophase, metaphase, anaphase, and telophase |
prophase | stage of mitosis which chromatin condenses into double rod-shaped structures |
sexual reproduction | where 2 morphological distant cells called gametes fuse together |
telophase | final phase where chromatids or chromosomes move to opposite ends |
