These are the condensing of chromatin into chromosomes, disintegration of the nuclear envelope, migration of centrosomes to either pole, and the reconstruction of the spindle apparatus.

They condense and become visible to light microscopy in prophase of mitosis or meiosis, and they decondense during interphase, in the form of chromatin (DNA wrapped around nucleosomes, like “beads on a string”). grapes of wrath chapter 30 quotes

"WebAnswer: In about 24 hour cycle of cell division, Interphase which is the phase between two successive M phases, lasts more than 95% of the duration of cell cycle (about 20-22 hours). Interphase includes G1, S and G2 phases of the cell cycle. M phase takes about approximately 1-2 hours of the cell cycle. " - In what phase do chromosomes decondense

Webchromosomes decondense during telophase II. sister chromatids are separated during anaphase II to become the chromosomes of the daughter cells. spindle microtubules … WebThe last phase of mitosis is telophase. During telophase, the chromosomes undergo decondensation. During decondensation, the DNA that is highly coiled gets uncoiled and gets freely dispersed in the nucleus and the chromosomes lose their identity. This leads to the formation of chromatin. Metaphase - Chromosomes align in the centre of the cell.

Webtelophase, or the stage at which the chromosomes reach the poles . The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells. What phase does the spindle apparatus breaks down? WebTelophase (the “distance phase”): the chromosomes reach the opposite poles and begin to decondense (unravel), relaxing once again into a stretched-out chromatin configuration. The mitotic spindles are depolymerized into tubulin monomers that will be used to assemble cytoskeletal components for each daughter cell.

WebIn this meiosis phase, the decondensation of chromosomes occurs., later the chromosomes are completely separated and the nuclear envelope forms.
