If you have a camera attachment for a microscope, photograph some of these cells and enlarge the pictures. Make copies of this and have the students do a karyotype. Since these cells are from the HeLa human tumor line, see if they can determine which chromosome is expressing multiple copies. Need data collection sheet similar to the template but without the chromosomes pictured. Provide different examples of the chromosome abnormalities for variety.
Specific instructions come with kit that can be reproduced.
An option would be to have already available photographs of slides of these tumor cells for students to karyotpye after they prepare their own slides. CellServ Program Rm. 103 McCort-Ward Bldg. Levitan, Max, 1988.
