But anyway, this first phase of mitosis, the nuclear envelope, the nuclear membrane starts to disappear. The centrosomes migrate to the opposite ends of the cell. And our DNA condenses into kind of the condensed form of the chromosomes. And we call this prophase. WebJan 12, 2024 · adibap20. Ans: Cyclins were discovered during a similar experiment to this one. The timing of the cell cycle is regulated by cyclins. When cytoplasm from a cell in mitosis is injected into another cell, the second cell enters into mitosis. The reason for this effect is a protein called cyclin, which triggers cell division. incentive\u0027s og

WebStudy with Quizlet and memorize flashcards containing terms like The centromere is a region in which A) chromatids remain attached to one another until anaphase. B) metaphase chromosomes become aligned at the metaphase plate. C) chromosomes are grouped during telophase. D) the nucleus is located prior to mitosis. E) new spindle microtubules form …

WebOne of the key differences in mitosis is a single cell divides into two cells that are replicas of each other and have the same number of chromosomes. This type of cell division is good for basic growth, repair, and maintenance. In meiosis a cell divides into four cells that have half the number of chromosomes. WebMitotic cyclins (cyclin A and cyclin B) contain a sequence motif known as the destruction box that is required for their destruction at the end of mitosis. Inactivation of mitotic cyclin–CDC2 complexes is important for events during exit from mitosis, including spindle disassembly, chromosome decondensation, cytokinesis, and reformation of ...
