Phage has outstanding characteristics as a research material for molecular genetics. There are many noted studies using phage. A mong them, the concepts of recon, muton, and cistron are famous, which were introduced by Dr. Benzer who studied the fine structure of phage.
Nowadays phage is a basis of research materials for molecular genetics, and it is widely used as a vector of DNA technology
Many biology textbooks used in high schools cover the experiment by Hershey and Chase who clearly proved that DNA is essential as a gene. D espite this fact, few productions of teaching materials for phage have been reported in the subject of biology. This author will develop the teaching materials for phage from following points.
1 What do we teach through phage ?
2 Appropriate themes of experiments and practical exploitaition of the teaching method
3 Examining the research assignments using phage
To make the points mentioned above clear, the following four experiments were made. Experiment 1: Examine the characteristics of genes
2: Examine the life cycle of phage using one-step growth
3: Examine cistron using cistrons complementation test
4: Make genetic maps using the three-point test and examine recon
These four experiments made by the students were successful with the expected results. The students’ reports proved that understood the experiments fully.
The summaries will be made in the following pages.
