Figure 5From: Resolution of complex ends by non-homologous end joining - better to be lucky than good?Trial and error. Ends can go through sequential rounds of end alignment (i) and processing (ii) (primarily nucleases; black Pac-man) until ligated. Alternatively, ends can be resected (iii) and Ku released, enabling resolution of ends by homologous recombination (HR) or alternative end-joining (Alt-EJ) pathways.Back to article page
