WebJun 17, 2024 · The evolution of organisms has provided a variety of mechanisms to maintain the integrity of its genome, but as damage occurs, DNA damage repair pathways are necessary to resolve errors. Among them, the DNA double-strand break repair pathway is highly conserved in eukaryotes, including mammals. Nonhomologous DNA end joining … WebMay 25, 2024 · CRISPR/Cas9 technology is a frequently used, highly efficient knock-in genetic editing tool. It takes advantage of the homology-driven DNA double-strand repair system to insert foreign DNA into a DNA double-strand break that is placed at a specific site by the high sequence specificity of the CRISPR/Cas9 endonuclease.

As necessary steps in this process, we describe the first successful genetic transformation and CRISPR/Cas9 genome editing in space. These milestones represent a significant … WebJun 10, 2024 · The location of this DNA distortion controls the location of RuvC-catalyzed target-strand cleavage, suggesting that Cas12a exploits local duplex instability to complete its double-strand break. This cleavage mechanism is likely shared by other DNA-targeting CRISPR-Cas12 systems, which all use a single RuvC active site to cut the target strand ...
WebSep 1, 2024 · CRISPR-Cas9 mediated homology directed repair (HDR), relies on the introduction of a double strand break in the gene of interest which is repaired by providing a homologous DNA fragment.
