[Answer] At which phase are centrioles beginning to move apart in animal cells?

Answer: prophase
At which phase are centrioles beginning to move apart in animal cells?

Tue Apr 19 2011 14:30:00 GMT-0400 (Eastern Daylight Time) · Centrosome separation. In early mitosis several motor proteins drive the separation of centrosomes. With the onset of prophase the motor protein dynein provides the majority of the force required to pull the two centrosomes apart. The separation event actually occurs at the G2/M transition and happens in two steps.

In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells .A bound pair of centrioles surrounded by a highly ordered mass of dense material called the pericentriolar material (PCM) makes up a structure called a centrosome.. Centrioles are not present in all eukaryotes; for example they are absent from …

During prophase in animal cells centrosomes move far enough apart to be resolved using a light microscope. Microtubule activity in each centrosome is increased due to recruitment of γ-tubulin. Replicated centrosomes from interphase move apart towards opposite poles of the cell powered by centrosome associated motor proteins.

These stages are prophase prometaphase metaphase anaphase and telophase. During mitosis the chromosomes which have already duplicated condense and attach to spindle fibersthat pull one copy of each chromosome to opposite sides of the cell.[4] The result is two genetically identical daughter nuclei.
