What is CRISPR Technology?
CRISPR technology is a revolutionary tool for genome editing and transcriptional modulation. It stands for Clustered Regularly Interspaced Short Palindromic Repeats and CRISPR-associated protein systems. CRISPR technology has also advanced molecular detection of diverse targets, ranging from nucleic acids to proteins. Incorporating CRISPR-Cas systems with various nucleic acid amplification strategies enables the generation of amplified detection signals, enrichment of low-abundance molecular targets, improvements in analytical specificity and sensitivity, and development of point-of-care (POC) diagnostic techniques. CRISPR technology has been used in various fields, including COVID-19 diagnosis and treatment.
How Does CRISPR Work?
CRISPR technology works by using a guide RNA to target a specific sequence of DNA, which is then cut by the Cas enzyme. This process can be used to edit genes, turn genes on or off, and even detect specific sequences of nucleic acids or proteins. The CRISPR-Cas system has various Cas proteins for their particular features, including RNA-guided endonuclease activity, sequence-specific recognition, multiple turnover trans-cleavage activity of Cas12 and Cas13, and unwinding and nicking ability of Cas9.

What is CRISPR Technology Used For?
CRISPR technology has various applications in different fields. It is used for gene editing, which is easier, cheaper, and more efficient than previous strategies for modifying DNA. CRISPR/Cas is being trialed as a new form of gene therapy for treating various human diseases, including cancers, and has aided drug development. As a diagnostic tool, CRISPR has been developed to aid the detection and screening of both human and plant diseases, and has even been applied during the current COVID-19 pandemic. In terms of agricultural breeding, precise targeting of biological pathways via CRISPR/Cas has been key to regulating molecular biosynthesis and allowing modification of proteins, starch, oil, and other functional components for crop improvement. CRISPR technology has also been used for chromatin and RNA targeting and imaging.

What Are Some Genetic Diseases That Can Be Treated with CRISPR?
CRISPR technology has the potential to treat various genetic diseases. The CRISPR/Cas9-mediated therapeutic approaches in human medicine can correct incurable genetic diseases and enhance cell-based therapeutic approaches. CRISPR/Cas9-based gene therapy has been extensively studied in preclinical and clinical treatments for treating human genetic diseases, including cardiovascular diseases, neuro-disorders, and cancers. CRISPR has the potential to treat various monogenetic diseases such as sickle cell disease, cystic fibrosis, and Tay-Sachs disease. However, significant challenges remain before CRISPR/Cas technology can be routinely employed in the clinic for treating different genetic diseases, which include toxicity and immune response of treated cells to CRISPR/Cas component, highly throughput delivery method, and potential off-target impact.
What Are The Ethical Concerns Surrounding CRISPR Technology?
CRISPR technology has raised various ethical concerns. One of the most contentious issues is the use of CRISPR for human germline modifications, which poses risks to human safety and morality such as the risk of unforeseen, undesirable effects in clinical applications, matter of informed consent, and the risk of exploitation for eugenics. There are also concerns about the off-target effects of CRISPR and the potential for designer babies and bio-weapons. To address these concerns, scientists are figuring out ways to minimize the risks and optimize the usage of CRISPR, such as using anti-CRISPR protein to minimize off-target effects and employing immunosuppressive drugs to address immunity issues. There is a need for worldwide debate and awareness to ensure responsible and wise use of CRISPR mediated genome editing technology. Some researchers have recommended an international ban on germline editing.
