WebHDR is a DSBR that uses a double-stranded DNA donor that has homology to the adjacent sequences surrounding the lesion to incorporate new DNA fragments. HDR offers more … WebHomology-directed repair (HDR) is a process where a DNA double-strand break (DSB) is repaired by homologous recombination using a DNA template. This template can come from within the cell during late S phase or G2 phase of the cell cycle, when sister chromatids are available prior to the completion of mitosis.
