This archival process serves as a biological memory, enabling the bacterium to mount a quick and efficient response to future attacks by the same virus. This sequence of events is akin to a soldier recalling the tactics of a previously encountered enemy, thus better preparing them for the next engagement.

Interestingly, when the bacterium is subsequently confronted with the same virus, it uses the stored CRISPR sequences to produce RNA molecules. These RNA guides then bind to the matching viral DNA, facilitating the introduction of double-strand breaks – essentially severing the invader's genetic material and neutralizing the threat. The implications of this discovery are profound, as it lays the groundwork for harnessing CRISPR in genetic editing.

Discovery of CRISPR Sequences

The actual identification of CRISPR sequences began in the late 1980s, during studies of the genome of Escherichia coli.
