BIOL 1201 : Bio Test 3 Learning Objectives
Document Summary
The specialized region of the chromosome where two sister chromatids are most closely attached. A structure of proteins attached to the centromere that links each sister chromatid to the mitotic spindle. The cell cycle proceeds by a defined sequence of events, where latter events depend on earlier events. The ultimate goal of the cell cycle is to distribute complete and accurate replicas of the genome to daughter cells. G1 checkpoint: check to see if dna is damaged. G2 checkpoint: check to see if dna is replicated properly. M checkpoint: spindle assembly checkpoint; check for alignment of chromosomes. The daughter strands of a duplicated chromosome, which are joined by a single centromere. When the centromere divides, the chromatids become separate chromosomes. Be sure you can complete the worksheets on cell division. Review the material in the cell division summary sheet. Haploid: a cell containing only one set of chromosomes (n)
