What phase do centromeres break?
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.
What phase is centrioles chromosomes and DNA duplicate?
Interphase
During which phase of meiosis do spindle fibers move the sister chromitatdes to the center of cells?
That would be anaphase I of meiosis. We know the question is concerning meiosis and not mitosis because it involves homologous chromosomes. Anaphase I begins when the kinetochore fibers stemming from the centrioles "grab" the centromeres of homologous chromosomes and "pull" them towards opposite ends of the cell.The mechanisms are a little more complicated than "grabbing" and "pulling," but for this question the mechanisms are of little importance.
What is the first phase of meiosis.?
Prophase
What pairs are correctly matched g1 phase-dna replication g2 phase-preparation for meiosis s phase- dna replication m phase-cell growth go phase-cell growth?
g2 phase-preparation for meiosis
In which phase do moving the pairs of centrioles to opposite poles?
The centrioles move toward opposite poles during prophase. During prophase the nuclear membrane disintegrates. Spindle fibers appear during the prophase.
What is the phase of mitosis or meiosis when choromose sperate to opposite ends of the cell?
In mitosis it is anaphase. In meiosis it is anaphase I and anaphase II.
What phase of meiosis does each replicated chromosome pair with its corresponding homologous chromosome?
Prophase 1 is the phase of meiosis ll when the homologous pairs combine. It is also when centrioles seperate, spindle fibers are formed, the nuclear envelope disappears, and the chromosomes become visible.
What phase in Meiosis do spindle fibers move homologous chromosomes to opposite sides?
Anaphase 1
Do centrioles organize the mitotic spindle in cell division?
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.
What phase happens in meiosis?
prophase1The first phase of meiosis is Prophase I
What phase happens first meiosis?
prophase1The first phase of meiosis is Prophase I

Anaphase is basically centromere splitting, where the spindle fibers from the centrioles split the chromosome in half at the centromere.
What stage of mitosis do the centrioles move to opposite ends of the cell?
Two centrosomes are arranged at opposite poles of the cell are called prometaphase.
The phase of mitosis in which doubling of the centrioles occurs is?
Centrioles double during the prophase of mitosis. Prophase is also the phase where DNA enters the chromosomes and are replicated.
What phase is centrioles chromosomes and DNA duplicate?
Interphase
Which phase occurs before mitosis or meiosis?
Inter-phase occurs before mitosis or meiosis.
