Do Centrioles Duplicate in Interkinesis?

In animal cells, during the S phase, DNA replication begins in the nucleus, and the centrioles duplicate in the cytoplasm. ... Centriole pairs also replicate in the interkinesis or intrameiotic interphase which is a metabolic stage between telophase I and prophase II or meiosis.

What happens during interkinesis phase?

During interkinesis, the single spindle of the first meiotic division disassembles and the microtubules reassemble into two new spindles for the second meiotic division. Interkinesis follows telophase I; however, many plants skip telophase I and interkinesis, going immediately into prophase II.

What phase do centrioles duplicate?

In 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. Procentrioles elongate until they reach the length of the parent centrioles in late G2.
