Origins of change. Heredity and mutation
Description
This program introduces the concepts of naturally occurring and artificially induced mutagens, demonstrates how X-radiation and chemical additives can produce genetic mutations, introduces Dr. Maclyn McCarty (one of three researchers who identified DNA as the substance that transformed one variety of Pneumococcus into another), and shows how DNA is extracted and precipitated. After viewing the program, students should understand why Drosophila melanogaster is so well-suited to genetic investigation, how mutation can be induced by chemicals, and how inherited variation is the result of a change in the genetic code of DNA.
