Full Answer
The centriole replicates during which stage of mitosis? The centrioles give rise to spindle fibres. Centrioles undergo duplication during S phase of the interphase. Failure of centrosome regulation can cause mistakes in chromosome segregation and is associated with aneuploidy.

The centrioles give rise to spindle fibres. Centrioles undergo duplication during S phase of the interphase. Failure of centrosome regulation can cause mistakes in chromosome segregation and is associated with aneuploidy.
S phaseIn most somatic cells, centriole duplication occurs during S phase and is marked by the formation of procentrioles at the proximal end of each parental centriole.
Microtubules, or 'daughter' centrioles, form at right angles near each 'mother' centriole. This mode of replication is termed semi-conservative and is similar to how DNA is replicated during this phase. The daughter centrioles grow in size during G2 phase, in preparation for cell division during mitosis.
S phaseS phase. In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.
S phaseI. G1 phase (Gap 1) - Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis) - Each of the 46 chromosomes are duplicated by the cell.
Centrioles undergo duplication during S phase of the interphase. Failure of centrosome regulation can cause mistakes in chromosome segregation and is associated with aneuploidy.
When it comes time for a cell to divide, the centrioles duplicate. During prophase, the centrioles move to opposite ends of the nucleus and a mitotic spindle of threads begins to appear. Those threads then connect to the now apparent chromosomes.
Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents.
During the G2 phase, extra protein is often synthesized, and the organelles multiply until there are enough for two cells. Other cell materials such as lipids for the membrane may also be produced. With all this activity, the cell often grows substantially during G2.
During interphase, the cell grows and DNA is replicated.
The G1 phase stands for gap 1 and is when organelles replicate and the cell grows. The S phase stands for synthesis and is when DNA is replicated.
During mitosis or cell division, the centrosome and centrioles replicate and migrate to opposite ends of the cell. Centrioles help to arrange the microtubules that move chromosomes during cell division to ensure each daughter cell receives the appropriate number of chromosomes.
During the S phase, the chromosomes, the centrosomes, and the centrioles (animal cells) duplicate. During the G2 phase, the cell recovers from the S phase, continues to grow, duplicates some organelles, and dismantles other organelles.
