A pair of ZFNs, each with three zinc fingers binding to target DNA, are shown introducing a double-strand break, at the FokI domain, depicted in yellow. Subsequently, the double strand break is shown as being repaired through either homology-directed repair or non-homologous end joining. [3]
The dimerization of two ZFNs is required to produce the necessary double-strand break within the CCR5 gene because the interaction between the FokI enzyme and DNA is weak. [11] This break is repaired by the natural repair mechanisms of the cell, specifically non-homologous end joining. [11]
Two ligands from a knuckle and two more from a short helix or loop. Treble clef: Two ligands from a knuckle and two more from the N-terminus of a helix. Zinc ribbon: Two ligands each from two knuckles. Zn 2 /Cys 6: Two ligands from the N terminus of a helix and two more from a loop. TAZ2 domain like: Two ligands from the termini of two helices.
dsDNA-break repair pathways and genome editing using CRISPR-Cas nucleases. A common form of genome editing relies on the concept of DNA double stranded break (DSB) repair mechanics. There are two major pathways that repair DSB; non-homologous end joining (NHEJ) and homology directed repair (HDR). NHEJ uses a variety of enzymes to directly join ...
A double-strand break repair model refers to the various models of pathways that cells undertake to repair double strand-breaks (DSB). DSB repair is an important cellular process, as the accumulation of unrepaired DSB could lead to chromosomal rearrangements, tumorigenesis or even cell death. [ 1 ]

Double-strand break repair models that act via homologous recombination. Homology-directed repair (HDR) is a mechanism in cells to repair double-strand DNA lesions. [1] The most common form of HDR is homologous recombination.
