The initial phase of mitosis; characterized by the appearance of chromosomes, the breakdown of the nuclear membrane, and the formation of the spindle apparatus.
Earliest stage in mitosis during which the chromosomes condense and the centrioles begin moving toward the spindle poles.
A stage at the beginning of mitosis or meiosis during which the chromosomes condense and become visible.
the first stage of mitosis during which the chromatid pairs form and aggregate around the equatorial region of the cell
The first stage of mitosis, meiosis I, and meiosis II, during which the chromosomes become visible and the centrioles move to opposite ends of the cell and begin to form the spindle.
the first phase of mitosis; involves chromosomal condensation, nuclear membrane breakdown, and the migration of centrioles to opposite poles.
pro = before + phasis = phase, from phainein = to appear, to show; first stage in mitosis of somatic cells.
(pro´ phase) • The first stage of nuclear division, during which chromosomes condense from diffuse, threadlike material to discrete, compact bodies.
(Greek, pro = before) The first phase of mitosis, when the diffusely stained chromatin resolves into discrete chromosomes, each consisting of two chromatids joined together at the centromere. (More? Week 1 Notes)
A stage in cell division when chromatin condenses into discrete chromosomes. The nuclear envelope breaks down and spindle fibers form at opposite "poles" of the cell.
stage of mitosis in which replicated chromosomes condense; nuclear membrane dissociates; centrioles migrate to the poles of the cell.
PRO-faze The first stage of cell division, when chromosomes condense and become visible. 171
The phase of a cell cycle marked by the emergence of the individual chromosomes from the undifferentiated mass of chromatin, indicating the beginning of mitosis.
1) The Þrst stage of mitosis during which chromosomes condense, the nuclear envelope disappears, and the centrioles divide and migrate to opposite ends of the cell. 2) The first stage of mitosis and meiosis (although in meiosis this phase is denoted with either a roman numeral I or II) where the chromatin condenses to form chromosomes, nucleolus dissolves, nuclear envelope dissolves, and the spindle begins to form. PICTURE
phase of mitosis in which the chromatin duplicates itself and thickens into chromosomes, the spindle fibers form, and the nuclear membrane disintegrates
the first stage of mitosis or meiosis.
(PRO-faze) The first of six phases of cell division. In prophase, chromosomes condense and become visible and the spindle forms.
The early stage of nuclear division during which chromosomes condense and become visible.
During mitosis, the stage at which the chromosomes become visible since the chromosome is longitudinally double except in the region of the centromere, the cell nucleus starts to lose its identity, and the centrioles divide and begin to migrate.
the phase of mitosis in which the duplicated chromosomes condense, the nuclear envelope dissolves, and centrioles divide and move to opposite ends of the cell.
One of phases of mitosis; two chromatids are linked at the centriole.
Prophase is a cell cycle stage of mitosis in which chromatin condenses into a highly ordered structure called a chromosome. It is at this stage giemsa staining can be applied to elicit G-banding in chromosomes. This process, called chromatin condensation, is mediated by condensin.
