![]() Table 1 lists the currently available software (standalone and web server) that used for designing sgRNA for CRISPR/Cas9 experiments. ![]() Software and web servers for designing sgRNA sequences Hence, to make the job easier for researchers around the globe, there is a need to keep an eye for various CRISPR design software based on some of the potential advantages, such as functionality, ease to use, its availability and more specifically research needs. Specifically, each has an advantage over the other. Although, several design tools, web servers, and databases exist not all of them are similar. 8ĬRISPR’s extensive applicability via gene editing and its easy rules for designing sgRNA has provided an excellent opportunity for bioinformatics researchers to get an insight of various aspects of CRISPR mechanism using computational approach and development of software that identifies potential sgRNA sequences in genomes. 7 CRISPR-Cas9 technology provides a precise method to improve industrially important microbial strains as cell factories (Eg: fermentation) for production of food, pharmaceutical, and biofuel products. The profound use of CRISPR-Cas9 technology has acknowledged by several researchers in generating accurate and efficient models of disease in cell lines, primary cells, and animal models. 6 CRISPR-Cas9 technology is a valuable tool in biological research specifically to modify genes through knockout studies, inserting specific sequences, up-regulation and down-regulation of genes. Also, through breeding crops with higher yields. In the case of agricultural biotechnology, the CRISPR-Cas9 technology aids in unraveling of both functional and phenotypical data about target plants and enhancing their resilience against drought and disease. ![]() 5ĬRISPR-Cas9 gene editing technology can generate transformative medicines in health sector such as the production of antimicrobials, animal health and therapeutic bio products. For simplification of the system for targeted mutations, a sgRNA with unique restriction sites for specific insertion of the target by combining endogenous tracrRNA and crRNA. 4ĬRISPR-Cas9 system is made of three components, viz: a small non-coding RNA called tracrRNA, a 20 nucleotide containing RNA sequence called crRNA that binds to the target DNA, and a RNA sequence repeat of 19-22 bases and a Cas protein encoding operon. Another advantage is the non-dependency on protein-based system such as ZFNs and TALENs. These inducible alterations in the genome provide a potential avenue for not only transferring traits in livestock and crops, but also to rectify diseased genes for human therapeutics with application in gene therapy. The advantage of CRISPR as a more reliable method is the ease in the creation of a break in the helical strand using RNA-guided nucleases that involve canonical base pairing between the target DNA region and the RNA designed for binding to it. 2 Among the various genome editing methods, TALENs, ZFNs, and CRISPR-Cas9 are the three foremost methods. 1 Consequently, many labs have tapped into the potential uses for this method and active research to unravel the mechanism has paved a unique path in the development of targeted genome editing techniques. To sustain against such predators, archaea and bacteria have evolved to have a new multilayered defense system that has been identified as CRISPR/Cas9. Specifically, the abundance of viruses attacking microorganisms is a constant threat in addition, the mutation and recombination rates in viruses make them fast-evolving predators. ![]() From an evolutionary point of view, archaea and bacteria have evolved to survive and blossom as communities in active environments that are, in general, stressful and unpredictable.
