| 例句 | Figure 6.4 Animal cell mitosis is divided into five stages—prophase, prometaphase, metaphase, anaphase, and telophase—visualized here by light microscopy with fluorescence. Concepts of Biology 2013-04-25T00:00:00Z The chiasmata remain until anaphase I. The number of chiasmata varies according to the species and the length of the chromosome. Biology for AP Courses 2022-06-09T00:00:00Z When anaphase I is complete, the separated chromosomes cluster at opposite ends of the cell. Miller & Levine Biology 2018-01-01T00:00:00Z What would happen if anaphase proceeded even though the sister chromatids were not properly attached to their respective microtubules and lined up at the metaphase plate? Anatomy and Physiology 2013-06-19T00:00:00Z The metaphase is the parting of the sister chromosomes in the equatorial plate; their passage to opposite poles of the spindle constitutes the anaphase; and their reconstruction to form the resting daughter nuclei, the telophase. Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 8 "Cube" to "Daguerre, Louis" 2012-01-31T03:00:17.257Z In anaphase I, the spindle fibers pull the linked chromosomes apart. Concepts of Biology 2013-04-25T00:00:00Z Aberrations caused when a pair of homologous chromosomes fails to separate during anaphase I or when sister chromatids fail to separate during anaphase II, the daughter cells will inherit unequal numbers of chromosomes. Biology for AP Courses 2022-06-09T00:00:00Z Mitosis is divided into four phases: prophase, metaphase, anaphase, and telophase. Miller & Levine Biology 2018-01-01T00:00:00Z The metaphase checkpoint ensures that all sister chromatids are properly attached to their respective microtubules and lined up at the metaphase plate before the signal is given to separate them during anaphase. Anatomy and Physiology 2013-06-19T00:00:00Z The first division is thus a reducing division, while the split appearing in the anaphase of the heterotype and presumably reappearing in the prophase of the homotype is the original split of the spireme thread. Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 8 "Cube" to "Daguerre, Louis" 2012-01-31T03:00:17.257Z In anaphase I, the homologous chromosomes are separated. Concepts of Biology 2013-04-25T00:00:00Z A Pair of chromosomes is pulled apart and migrate towards pole in anaphase I, while in anaphase II sister chromatids separate. Biology for AP Courses 2022-06-09T00:00:00Z In anaphase, the chromosomes separate and move to opposite ends of the cell. Miller & Levine Biology 2018-01-01T00:00:00Z As in all the beetles so far studied there is no rest stage between the two maturation divisions, but the late anaphase of the first mitosis passes over quickly into the second spindle. Studies in Spermatogenesis Part II The anaphase of the same mitosis is shown in figures 217 and 218; it is peculiar in that one chromosome always divides more slowly than the others, the two elements hanging together at one end. Studies in Spermatogenesis Part I During anaphase II, as in mitotic anaphase, the kinetochores divide and one sister chromatid is pulled to one pole and the other sister chromatid is pulled to the other pole. Concepts of Biology 2013-04-25T00:00:00Z Pairs of chromosomes are pulled apart and migrate towards the poles during anaphase I, while in anaphase II sister chromatids separate. Biology for AP Courses 2022-06-09T00:00:00Z During anaphase, the chromosomes separate and move along the spindle fibers to opposite ends of the cell. Miller & Levine Biology 2018-01-01T00:00:00Z First spermatocyte, anaphase, showing elongated centrosome and diverging univalent chromosomes. Studies in Spermatogenesis Part II Late anaphase, showing element x double in 129, and a lagging tetrad in 130. Studies in Spermatogenesis Part I In cells such as animal cells that lack cell walls, cytokinesis begins following the onset of anaphase. Concepts of Biology 2013-04-25T00:00:00Z Pair of chromosomes are pulled apart and migrate towards the poles in anaphase I, while in anaphase II sister chromatids separate. Biology for AP Courses 2022-06-09T00:00:00Z In cells such as animal cells that lack cell walls, cytokinesis starts during late anaphase. Biology for AP Courses 2022-06-09T00:00:00Z An anaphase including the small chromosome is shown in figure 56. Studies in Spermatogenesis Part II Figure 195 is a later anaphase containing the divided small chromosome. Studies in Spermatogenesis Part I Mitosis consists of five stages: prophase, prometaphase, metaphase, anaphase, and telophase. Concepts of Biology 2013-04-25T00:00:00Z Draw sister chromatids at anaphase II for both parents in the F1 generation and annotate your drawing to identify each genotype of the gametes using the cells of the Punnett square. Biology for AP Courses 2022-06-09T00:00:00Z Errors during anaphase I of meiosis only cause such aberrations resulting in unequal numbers of chromosomes. Biology for AP Courses 2022-06-09T00:00:00Z In the anaphase of the second division all of the chromosomes are divided quantitatively as may be seen in figures 77 and 78. Studies in Spermatogenesis Part II The latter is a view of the anaphase which one often gets at three foci in one section. Studies in Spermatogenesis Part II An early anaphase of this mitosis is shown in figure 19; here the small chromosome is already divided. Studies in Spermatogenesis Part II Each pair of chromosomes is pulled apart and migrate towards the poles in anaphase I, while in anaphase II sister chromatids separate.
