Crispr-based adaptive immune systems
WebCRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a genome editing system that was first discovered in bacteria as an adaptive immune response against invading bacteriophages. 1 A naturally occurring CRISPR sequence consists of tracrRNA (trans-activating CRISPR RNA), and a short piece of RNA, called crRNA. 2 These two … WebCRISPR: An Adaptive Immune System. ... Makarova et al. ’s classification defines 5 types and 16 subtypes based on shared characteristics and evolutionary similarity. These are grouped into two large classes based on the structure of the effector complex that cleaves the genomic DNA. Type II CRISPR was the first system harnessed for genome ...
