Learning Goals: 1. To affix, stain and visualize human chromosomes mounted on microscope slides. 2. To recognize various chromosomal features (sister chromatids and centromeres). 3. To recognize size differences among the chromosomes. 4. To recognize the 3 basic human chromosome morphologies based on centromere position.
Key Concepts: HeLa cells, chromosomes and chromosome number, centromeres, mitosis, hypotonic solutions, slide staining and preparation, cancer, DNA, microscope use.
