title: A novel deletion found during cloning of a synthetic palindromic DNA.
abstract: A 212-bp palindromic DNA comprising two copies of the left end of bacteriophage Mu was assembled from chemically synthesized oligonucleotides and inserted into plasmid pUC9. When cloned and propagated in Escherichia coli, the palindrome was found to be unstable and was generally lost. However, in a few cases, a precise, asymmetric deletion of one half of the insert was observed. This pattern of deletion suggests that the symmetry axis region of the palindrome was involved as recognition site in the deletion process.
