1 Mutagens מוטגנים Radiation קרינה Chemical Agents חומרים כימיים Mobile Genetic Elements אלמנטים DNA ניידים

2 gal -, due to insertion OR “disruption” REVERTANT: gal + revertant, due to excision of IS1 Insertion elements : insertion elements as mutagens

3

4 (Ampicillin resistance)

5

6 Conservative Replicative

7 Animation 13_Replicative transposition

8 Mutagens מוטגנים Radiation קרינה Chemical Agents חומרים כימיים Mobile Genetic Elements אלמנטים DNA ניידים

9 Inexact excission of IS1 can also create gal -
