Question
Relate the following events, structures, molecules, etc. to one another and to the segregation of chromosomes into daughter cells in Mitosis and Meiosis. Mitosis Centromere Sister chromatids Spindle apparatus Meiosis Homologous chromosomes Length of the chromosomes Synaptonemal complex Number of chromosomes in a cell Chromosome condensation Relate these items to chromosome segregation and to one another, briefly and succinctly in one or two coherent paragraphs. Ik specific; don't use vague generalities. Identify- all relationships, not just the most obvious ones. Do not simply define each term and do not write a separate paragraph about each item.Explanation / Answer
Try these ideas and rewrite into your style For both mitosis and meiosis, DNA replication occurs prior to the event. For both, chromatin condenses into chromosomes, the nucleolus dissolves, nuclear membrane is disassembled, and the spindle apparatus forms. the chromosomes condense as well. In meiosis, homologous chromosomes pair up, facilitated by assembly of central element of the synaptonemal complex align themselves along the metaphase plate, Spindle fibers attach to the centromere region of each homologous chromosome pair.and are drawn to opposite ends of the cell. Other metaphase events as in mitosis. the tetrads separate, and are drawn to opposite poles by the spindle fibers. the centromeres split and the former chromatids (now chromosomes) are segregated into opposite sides of the cell. For Meiosis a second division then occurs producing 4 haploid cells .Meiosis reduces the number of sets of chromosomes by half . Mitosis is a single cell division resulting in two diploid cells with the same number of sets of chromosomes
