| Popis: | Three derivatives of mutant ga10P-308::IS2-I of Escherichia coli were characterized by DNA sequence analysis. Deletions and DNA sequence rearrangements were observed which apparently were initiated at short A-T rich inverted repeats within IS2. Two of the mutants carried newly synthesized DNA sequences which were inverted copies of already existing IS2 sequences. Thus long stretches with twofold symmetry were formed. It is discussed whether these inverted repeats were formed by DNA repair synthesis which was initiated at the A-T rich palindromes of IS2. |
