Clustered Regularly Interspaced Short Palindromic Repeats
Short Palindromic Repeats
segments of DNA containing short, repetitive base sequences
In a palindromic repeat, the sequence of nucleotides is the same in both directions
Nucleobases of DNA
Nucleotide = Nitrogenous base + Pentose + Phosphate
Pentose = Sugar (monosaccaride)
Nucleoside = Nitrogenous base + Pentose
Nucleobase = Nitrogenous base
Clusterly Regularly Interspaced
by so called "Spacers" = Spacer DNA
Spacer DNA = intergenic spacer (IGS) is a region of non-coding DNA between genes
snippets of DNA from viruses that have attacked the bacterium.
CRISPR/Cas System
prokaryotic bacteria immune system against foreign genetic elements
Cas = CRISPR Associated Genes
Gene = A sequence of DNA/RNA
encode proteins that mediate the defense process
Nuclease Proteins (cut DNA)
Helicase Proteins (unwind DNA)
