noun Biochemistry
1A segment of DNA containing short repetitions of base sequences, involved in the defence mechanisms of prokaryotic organisms to viruses.
  • CRISPR sequences encode RNAs that can recognize specific target sequences in a genome, at which base pairs can be cut or added. They act in a complex with a specific protein that functions like a pair of molecular scissors, with which they are used as a tool in genetic engineering.
The majority of identified <EM>CRISPR</EM> loci are associated with a set of conserved protein-encoding genes termed cas (CRISPR-associated genes)....
  • Researchers detail in 'H-NS-mediated repression of CRISPR-based immunity in Escherichia coli K12 can be relieved by the transcription activator LeuO,' new data in Escherichia coli.
  • The genome of P. carbinolicus contains clustered regularly interspaced short palindromic repeats (CRISPR) separated by unique spacer sequences.
1.1A genetic engineering tool that uses a CRISPR sequence of DNA and its associated protein to edit the base pairs of a gene: using the genome editing tool known as CRISPR, researchers were able to selectively silence two genes in human papilloma virus...
  • The CRISPR Design Tool was developed by the Feng Zhang laboratory at MIT.
  • The CRISPR/Cas9 design algorithm at this site allows users to input DNA sequence.
  • This limited the CRISPR system to its minimal functional components and thus illuminated its potential as a powerful genome editing tool.
