Τι (ποιος) είναι Telophase - ορισμός

THE CELL CYCLE PHASE WHICH FOLLOWS ANAPHASE DURING M PHASE OF MITOSIS AND MEIOSIS AND DURING WHICH THE CHROMOSOMES ARRIVE AT THE POLES OF THE CELL AND THE DIVISION OF THE CYTOPLASM STARTS.
Telephase; Teleophase
  • Stages of late M phase in a vertebrate cell
  • Fluorescence micrograph of a human cell in telophase showing chromosomes (DNA) in blue, microtubules in green and kinetochores in pink
  • This image describes the final stage in mitosis, telophase.

telophase         
['ti:l?(?)fe?z, 't?l-]
¦ noun Biology the final stage of cell division, between anaphase and interphase, in which the two daughter nuclei are formed.
Origin
C19: from Gk telos 'end' + phase.
Telophase         
Telophase () is the final stage in both meiosis] and [[mitosis in a eukaryotic cell. During telophase, the effects of prophase and prometaphase (the nucleolus and nuclear membrane disintegrating) are reversed.
zygotene         
  • A video of meiosis I in a [[crane fly]] [[spermatocyte]], played back at 120× the recorded speed
  • Meiosis Prophase I in mice. In Leptotene (L) the axial elements (stained by SYCP3) begin to form. In Zygotene (Z) the transverse elements (SYCP1) and central elements of the synaptonemal complex are partially installed (appearing as yellow as they overlap with SYCP3). In Pachytene (P) it's fully installed except on the sex chromosomes. In Diplotene (D) it disassembles revealing chiasmata. CREST marks the centromeres.

Telophase

Telophase (from Ancient Greek τέλος (télos) 'end, result, completion', and φάσις (phásis) 'appearance') is the final stage in both meiosis and mitosis in a eukaryotic cell. During telophase, the effects of prophase and prometaphase (the nucleolus and nuclear membrane disintegrating) are reversed. As chromosomes reach the cell poles, a nuclear envelope is re-assembled around each set of chromatids, the nucleoli reappear, and chromosomes begin to decondense back into the expanded chromatin that is present during interphase. The mitotic spindle is disassembled and remaining spindle microtubules are depolymerized. Telophase accounts for approximately 2% of the cell cycle's duration.

Cytokinesis typically begins before late telophase and, when complete, segregates the two daughter nuclei between a pair of separate daughter cells.

Telophase is primarily driven by the dephosphorylation of mitotic cyclin-dependent kinase (Cdk) substrates.
