New deletion mutant of bacteriophage T5.

摘要: Deletion mutants of bacteriphage T5 can be identified by analyzing the DNA content single plaques, after alkaline denaturation, agarose gel electrophoresis. Use this procedure has resulted in isolation a new mutant, designated del2, that lacks 1.6% segment located 68 to 70% from left end DNA. This occurs between early and late gene regions
