Cas variants increased the dimension of the CRISPR tool kit

Abstract

CRISPR technology shows promising developments in multiple areas of biological sciences. It is a developing technology and continuously evolving day by day. Cas proteins, an integral component of CRISPR technology, has enormous scope for new discoveries and reengineering. It can enhance new dimensions in CRISPR tool kit. In this chapter, we systematically explain the classification of CRISPR-Cas system. We separately compiled applicability of different CRISPR-Cas system. In the end, we discussed about the advancement and reengineering of available CRISPR-Cas systems.
