abnormal double-strand break repair during vegetative growth altered double-strand break repair junction in presence of persistent double-strand breaks abnormal double-strand break repair resulting in formation of altered repair junction FYPO:0003928 midori altered pattern of repair junctions in HO survivors This phenotype is commonly assayed using continuous expression of the HO endonuclease, and in mutant cells that survive constitutive DNA cleavage by HO, break repair patterns differ from those in wild type HO survivors. A cell phenotype in which the repair of double-strand breaks in DNA that are continually made (for example, by constitutive expression of a nuclease) results in repair junctions that differ from wild type. 2014-10-28T16:28:47Z
