Study Guide Bio 22 Final. Binary Fission: Chromosome attatches to the plasma membrane Chromosome replicates Cell grows, Protein ring is formed (FtsZ) Ring constricts, the membrane and cell wall infold Fission complete. Mitosis: Gap 1: chromosomes replicate Interphase: they are already replicated, the centrosomes replicate. Prophase: the chromosomes condense and the miotic spindle fibers forms Prometaphase: nuclear envelope breaks down and the spinds fibers attatch to the chromosomes at the kinetochore. Metaphase: the chromosomes migrate to the middle Anaphase: the chromotids separate and chromosomes go to opposide poles Telephase: nuclear envelope re-forms and the spindle apparatus disintegrates Cell divison: cytokinesis, the cell is divided into to daughter cells. Gap 2: cells do their job Meiosis: diploid (2N) to haploid (N) (genetic variation through crossing over/recombination) Interphase: chromosomes replicate Early prophase: chromosomes condense, nuclear envelope breaks up, spindle apparatus forms, synapsis of chromosomes Late Prophase: crossing over occurs between non sister chromatids Metaphase: the tetrads migrate to the middle Anaphase: homologs separate and begin moving to opposide sides of cell Telephase: chromosomes move to opposide sides of the cell; cell divides (cytokinesis) Prophase II: centrosomes replicate and spindle apparatus forms Metaphase II: chromosomes line up at the middle of cell (plate) Anaphase II: sister chromatids separate and move to opposite sides of the cell Telophase II: chromosomes move to opposite sides and cell divides (cytokinesis) Dihybrid cross: 9:3:3:1 (independent assortment) Frequency of recombinant offspring for genetic distance map: total#recomb/total pop x
