Crispr array meaning
WebA CRISPR-Cas system consists of a Cas gene and its associated CRISPR arrays of repetitive sequences (direct repeats) interspaced by nonrepetitive DNA sequences (spacers) derived from non-self-DNA material. The CRISPR repetitive sequences are transcribed into short RNAs and termed CRISPR RNAs (crRNA). Cas proteins bind to these crRNAs to …

CRISPR (short for “clustered regularly interspaced short palindromic repeats”) is a technology that research scientists use to selectively modify the DNA of living organisms. CRISPR was adapted for use in the laboratory from naturally occurring genome editing systems found in bacteria.
WebCRISPR-Cas systems typically consist of a CRISPR array and cas genes that are organized in one or more operons. However, a substantial fraction of CRISPR arrays are not adjacent to cas genes. Definitive identification of such isolated CRISPR arrays runs into the problem of false-positives, with unrelated types of repetitive sequences mimicking CRISPR.
