BOT 1010L Lecture Notes - Lecture 8: Nuclear Membrane, Centromere, Nucleolus
Document Summary
__________ refers to the process of cellular division that produces 2 daughter cells with equal amounts of dna and other substances duplicated during interphase. ---each daughter cell is an exact copy of the parent cell. ( 1 diploid cell --> 2 diploid cells) (1 haploid cell --> 2 haploid cells) In ____________ strands of _________ coil and tighten with centromeres holding each pair of chromatids together. ______________ develop and become attached to the centromere . In _____________ chromosomes align at the cells equator. Spindle fibers collectively referred to as the spindle. At the end of this phase, the centromeres holding each sister chromatid separate lengthwise. In _______________ sister chromatids separate and are pulled to opposite poles. Spindle fibers gradually shorten as material is continuously removed from the polar ends. In __________________ each group of daughter chromosomes become surrounded by a nuclear envelope that re-forms. ________ - permanent regions of active cell division.
