Definitions and meanings of "Prophase"

What do we mean by prophase?

The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell. noun

The first stage of meiosis, constituted by a series of events that include the thickening and coiling of the chromosomes, synapsis of homologous chromosomes, tetrad formation, and crossing over. noun

In cytology, a preparatory stage in mitotic cell-division. The prophase is characterized by a more intense staining of the chromatin, the resolution of the reticulum into a skein or spireme, the breaking up of the latter into chromosomes, the appearance of the achromatic spindle, and the disappearance of the nuclear wall. The prophase is succeeded by the metaphase. noun

The first stage of mitosis, during which chromatin condenses to form the chromosomes noun

The first stage of meiosis noun

The first stage of mitosis noun

The first stage of meiosis noun

The first stage of mitosis, during which chromatin condenses to form the chromosomes.

The first stage of meiosis.

The word "prophase" in example sentences

Prophase - The first stage of mitosis is known as prophase, where the nuclear chromatin starts to become organized and condenses into thick strands that eventually become chromosomes observable in the optical microscope (Figure 1 (b)).

A crossover at the meiotic prophase, as shown in Fig. 2, produces a dicentric chromosome that simulates two normal chromosomes attached together at the ends of their short arms, and a fragement chromosome with telomeres at both ends. ❋ Unknown (1983)

Its "epigenesis" is shown to be a literary example of the phases of cell division, with discussions of its prophase, metaphase, anaphase, and telophase. ❋ Rothstein, Edward (1979)

Even in the middle of the twentieth century, textbooks and teachers could still be found perpetuating this error, in spite of the fact that a careful look at Flemming's own figures of nuclei in early prophase shows quite clearly that more than two chromosome ends are apparent in various prophase nuclei! ❋ BENTLEY GLASS (1968)

This conception, which was based simply on inadequate observations of the number of free chromosome ends in the early prophase nuclei, was less in conflict with any of the principles of genet - ics, and had a much longer life. ❋ BENTLEY GLASS (1968)

I to III, prophase; IV, metaphase; V and VI, anaphase; VII and VIII, telophase. ❋ Unknown (1918)

Bardhan A, Chuong H, Dawson DS (2010) Meiotic cohesin promotes pairing of non-homologous centromeres in early meiotic prophase. ❋ David Obeso Et Al. (2010)

A requirement for Zip1 in initiation of coupling would predict that coupling would not be observed at any time point, whereas a role in maintenance could result in the observation of centromere coupling at early time points that does not persist until late meiotic prophase. ❋ David Obeso Et Al. (2010)
