Was passiert in der G1-Phase?
Die Interphase startet mit der G1-Phase, auch Gap-Phase genannt. Sie schließt sich direkt an die vorige Cytokinese an. Bei ihr bereitet sich die Zelle auf die Zellteilung vor und wächst stark an. Zellorganellen und Zellplasma werden durch eine verstärkte Proteinbiosynthese gebildet.
Was findet während der G1-Phase statt?
In der G1-Phase (G für englisch gap ‚Lücke‘), die sich direkt an die Zellteilung (Zytokinese) anschließt, kommt es zu Zellwachstum und Bildung von Organellen mit Proteinbiosynthese und RNA-Synthese. In der nachfolgenden S-Phase (Synthese-Phase) findet die Replikation der DNA bzw. die Verdoppelung der Chromatiden statt.
What are some facts about telophase?
telophase A stage of cell division. In mitosis the chromatids that separated from each other at anaphase collect at the poles of the spindle. A nuclear membrane forms around each group, producing two daughter nuclei with the same number and kind of chromosomes as the original cell nucleus.
What is the end result of telophase?
During telophase I of meiosis, the chromosomes decondense and cytokinesis comes to an end. Cytokinesis refers to the division of the cytoplasm, which results in two haploid daughter cells at the completion of telophase I.
What is the difference between anaphase and telophase?
Anaphase follows telophase. The main difference between anaphase and telophase is that the chromosomes are pulled to the opposite poles of the cell during anaphase whereas nuclear envelopes are formed surrounding the two daughter nuclei during telophase. Prophase and metaphase are the foremost events of cell division.
What is the main event in telophase?
The main events of meiosis include prophase, metaphase, anaphase and telophase. A cell in meiosis goes through two divisions, meiosis I and meiosis II, in which each division consists of the same stages to produce gametes or sexual reproduction cells.
