Mitose: Prophase, Metaphase, Anaphase, Telophase und ...
Die aus zwei identischen Chromatidsträngen bestehenden Chromosomen (in der Abbildung die roten X im braunen Zellkern) verkürzen und verdichten sich, indem sie im Zellkern aufgefaltet werden.
Metaphase
Metaphase (from the Greek μετά, "adjacent" and φάσις, "stage") is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second most condensed and coiled stage (they are at their most condensed in anaphase). These chromosomes, carrying genetic information, align in the equator of the cell before being ...
Interphase
Stages of interphase. There are three stages of cellular interphase, with each phase ending when a cellular checkpoint checks the accuracy of the stage's completion before proceeding to the next.
Meiosis I Stages: Prophase I, Metaphase I, Anaphase I ...
Prophase I is the first step in meiosis I. And a lot happens during this step, some of which is a departure from what we saw in mitosis. During prophase I, the chromatin condenses.
Mitose –
Im Zellzyklus sich teilender Zellen von Eukaryoten sind Kernteilung und Zellteilung aneinander gekoppelt. Mitose und Zytokinese werden so zusammen auch als Mitose oder M Phase bezeichnet.
Mitose — Wikipédia
Les phases de la mitose. La mitose est un phénomène continu, mais pour faciliter la compréhension de son déroulement les biologistes ont décrit cinq étapes caractéristiques de la mitose qui sont la prophase, la prométaphase, la métaphase, l'anaphase et la télophase.

LabBench Activity Mitosis and Meiosis. by Theresa Knapp Holtzclaw. Introduction. For organisms to grow and reproduce, cells must divide. Mitosis and meiosis are both processes of cell division, but their outcomes are very different.
meiose Athénée Fernand Blum
4 Avantage évolutif de la sexualité et de la méiose. Les phénomènes de reproduction et de sexualité ne sont pas systématiquement liés. La reproduction, seule présente dans les actes de reproduction asexuée, a pour seul objectif de multiplier les individus et de perpétuer l'espèce.
