The centrioles move toward opposite poles during prophase. During prophase the nuclear membrane disintegrates. Spindle fibers appear during the prophase.
No they do not, centrioles are the only organelles in a cell which are not synthesised during the G1 phase. During the telophase of cell division the two pairs of centrioles in each of their own centrosomes break down. Whilst a new nuclear memebrane is forming around the chromosomes a new par of centrioles is synthesised. Therefore centrioles are made during the telophase of the mitotic phase. Centrioles then divide into two pairs during the Synthesis phase. Each pair of centrioles then move to opposite poles of the nucleus during prophase.
During this phase of mitosis, known as prophase, the centrioles move to opposite poles of the cell. As the centrioles migrate, they begin to form the mitotic spindle, the structure that will help separate the chromosomes during cell division.
The phase of mitosis in which doubling of the centrioles occurs is the G1 phase. During this phase, the centrioles replicate to ensure that each daughter cell will receive a complete set of centrioles.
Centrosomes replicate during the S phase of the CELL CYCLE not mitosis. Mitosis is one stage of the cell cycle. Replication does not happen during mitosis(M phase). It happens during the S phase. In fact, the opposite happens chromosomes are consdensed and packaged in preparation for splitting.
Centrioles are duplicated during the S phase of the cell cycle, specifically in the G1 phase.

During the cell cycle, centrioles are duplicated during the S phase of interphase. Each centriole serves as a template for the formation of a new centriole, resulting in two pairs of centrioles, one for each daughter cell after cell division. This duplication process ensures that each daughter cell receives an equal number of centrioles.
Centrioles are duplicated during the S phase of the cell cycle, specifically in the G1 phase.
The centrioles move to opposite ends of the cell during the prophase stage of mitosis. This movement is essential for the formation of the mitotic spindle, which helps separate the duplicated chromosomes during cell division.
Interphase
The presence of two centrioles on one side of the nucleus indicates that the cell is in the prophase stage of mitosis. During prophase, the centrioles move to opposite poles of the cell, forming the mitotic spindle that will help separate the chromosomes during cell division.
Centromere splitting is something that happens to the Chromosomes during the M Phase (Mitosis) of cell division. During Anaphase (a phase in the M Phase), the centrioles that have sent out spindle fibers and are at opposite poles just tug at the centromere of the Chromosome, causing the centromere to split. Anaphase is basically centromere splitting, where the spindle fibers from the centrioles split the chromosome in half at the centromere.
because the most things happen in it. centrioles grow, spindle fibers arrange on chromosomes, and the cell grows exponentially.
