Fig. 1From: CRISPR-Cas9 mediated phage therapy as an alternative to antibioticsThe CRISPR-Cas adaptive immunity. During adaptation phase Cas1-Cas2 complex selects spacer and incorporates to the upstream of CRISPR locus. At crRNA biogenesis phase, the locus transcribes pre-crRNA which forms tracr-RNAs that helps in the recognition by RNase III and cutting process during the interference phaseBack to article page
