Webpotential gRNA off-target sites. In fact, the large speedups possible with the AP motivate the possibility of automata-based solutions even on the CPU. In this paper, we propose COAT-AP, an automata-based so-lution, to quickly ﬁnd potential off-target sites by allowing any Hamming distances. Fully exploiting the massive parallelism WebThe gRNA is made up of two parts: crispr RNA (crRNA), a 17-20 nucleotide sequence complementary to the target DNA, and a tracr RNA, which serves as a binding scaffold for the Cas nuclease. The CRISPR-associated protein is a non-specific endonuclease. It is directed to the specific DNA locus by a gRNA, where it makes a double-strand break.
