Therefore, the technologies for the genome editing is undergoing various advancements, the most recent advancement for the genome editing is utilizing the nucleases which include the zinc finger nuclease (ZFN), transcription activators like effector nuclease (TALEN) and (clustered regulatory interspaced short palindromic repeats) CRISPR Cas9 system.

By contrast, HDR enables precise insertion of a transgene into the targeted region if the donor DNA template contains the desired transgene flanked by sequences that are homologous to the regions either side of the cleavage site and is co-delivered into the cell along with the nuclease. Genome editing approach using optimized endonuclease systems, such as ZFN, TALEN, and CRISPR/Cas9, are successfully used for generation of both knock-out and knock-in cultured cells and animal strains.

The funds will be used by Emendo to further advance its novel nuclease gene editing discovery platform and proprietary product development programmes.

Cas9 is one type of the nuclease in CRISPR system that can be directed to specific genome sites by a small RNA named guide RNA (gRNA).

In this regard, to facilitate the selection of the target sites for nucleases and experimental verification of the presence of nontarget effects, several software packages were developed that enable nuclease design and validation [79, 87, 90].

1A) uses the strong preference of a thermostable duplex-specific nuclease (DSN) toward digestion of dsDNA over single-stranded DNA (29).

The major limitation with CRISPR/Cas9 is the need of PAM sequences to target and link the nuclease. Two approaches to solve this issue include expanding the number of PAM sequences using sequences from various bacteria and by modifying the PAM sequence specificity of S.
