the region of duplicated chromosome where two sister chromatids are joined and where spindle microtubles attach during mitosis and meiosis.
Material in the cytoplasm of the eukaryotic cell that gives rise to microtubules
the combination of DNA and proteins that constitutes eukaryotic chromosomes, often used to refer to the diffuse, very extended form taken by chromosomes when a cell isnt dividing.
the reproduction of a cell through a duplication of the genome and divsion of the cytoplasm
the fourth stage of mitosis, beginnign when the sister chromatids seperate from each other and ending when a complete set ofdaughter chromosomes arrives at each of the two poles of the cell
an ordered sequence of events (including interphase & the mitotic phase) that extends from the time a eukayotic cell first formedfrom a dividing parent cell until its own divison into two cells.
the third stage of mitosis, during which all the cell's duplicated chromosomes are lined up at an imaganry plane equidistant between the poles of the mitotic spindle
a means of asexual reproduction in which a parent organism, often a single cell, divides into two genetically identical individuals of about equal size
the second stage of mitosis, during which the nuclear envelope fragments and the spindle microtubles attach to the kinetchores of the sister chromatids
the first stage of mitosis, during which the chromatin condenses to form structures (sister chromatids) visible with the light microscope and the mitotic spindle begins to form, but the nucleus is still intact
