Plk1 supports the functional maturation of the centrosome in late G2 / early prophase and establishment of the bipolar spindle.
22.
The encoded protein localizes to prophase kinetochores before ZW10 does and it remains detectable on the kinetochore until late anaphase.
23.
During prophase, two aster-covered centrosomes migrate to opposite sides of the nucleus in preparation of mitotic spindle formation.
24.
The nucleolus starts moving towards the nuclear membrane at the beginning of prophase, and its disintegration occurs near the nuclear envelope.
25.
Chromomeres are organized in a discontinuous linear pattern along the condensed chromosomes ( pachytene chromosomes ) during the prophase stage of meiosis.
26.
Primordial follicles containing the primary oocyte, arrested at prophase of meiosis I, develop into primary follicle containing cuboidal granulosa cells.
27.
Therefore, the early stages in the cell cycle, beginning in prophase and until around prometaphase, the nuclear membrane is dismantled.
28.
In chromosomal crossovers, non-sister ( homologous ) chromatids form chiasmata to exchange genetic material during the prophase I of meiosis.
29.
During prophase, as the chromatin condenses so that it is visible under the microscope, survivin starts to move to the centromeres.
30.
During zygotene phase of prophase I, the chromomeres of homologs align with each other to form homologous rough pairing ( homology searching ).
