Mitosis Structures
| Question | Answer |
|---|---|
| Chromosome | A structure composed of a DNA molecule and associated proteins |
| Chromatin | The material that makes up eukaryotic chromosomes. Consists of a DNA molecule complexed with histone proteins |
| Chromatid | One strand of a replicated chromosome, with its associated proteins |
| Sister chromatids | The two strands of a replicated chromosome. when chromosomes are replicated, they consist of two sister chromatids. the genetic material in sister chromatids is identical. when sister chromatids separate during mitosis, they become independent chromosomes |
| Centromere | The structure that joins sister chromatids |
| Kinetochore | The structure on sister chromatids where spindle fibers attach |
| Microtubule organizing center | Any structure that organizes microtubules |
| Centrosome | The microtubule organizing center in animals |
| Centriole | Cylindrical structures that comprise microtubules, located inside animal centrosomes |
