Developments in CRISPR-Cas
In the preceding years, CRISPR-Cas systems have been extensively studied and substantially modified, expanding the range of possible genome modifications through various modes of action, and improving target specificity. This section strives to provide an overview of the most important advancements in CRISPR-Cas9 and CRISPR-Cas12a systems. You can view the following sub-sections in any order.
