The meaning of PROPHASE is the initial stage of mitosis and of the mitotic division of meiosis characterized by the condensation of chromosomes consisting of two chromatids, disappearance of the nucleolus and nuclear membrane, and formation of mitotic sp
1.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. 2.The first stage of meiosis, constituted by a series of events that include the thickening and coiling of ...

Prophase is the first step of cell division in both mitosis and meiosis. Cells undergo mitosis in order for the organism to be able to grow, develop and repair. Think about what happens when you cut your skin; it takes time for the wound to heal. Part of the healing process is your ...
Mitosis and meiosis are both processes of eukaryotic cell division, with the same names used to describe different stages. What are the similarities and differences between the events that occur during each stage of mitosis and the corresponding stage of ...
Cohesins are ancient and ubiquitous regulators of chromosome architecture and function, but their diverse roles and regulation remain poorly understood. During meiosis, chromosomes are reorganized as linear arrays of chromatin loops around a cohesin axis

Such a phenomenon was observed during meiosis in yeast [11], spermatogenesis in animals [14], and during meiosis and the development of microsporocytes in plants [12,13]. In all these cases the mechanism involves intron retention. In pre-mRNAs usually only one or two introns are left and...
