Answer:

CRISPR-Cas13 is a bacterial defense system that acts as a pair of scissors to detect diseases. Much like Cas9, it uses a gRNA to find its viral target but what is unique about this protein is that once it binds, it becomes activated and cuts any RNA it encounters, much like a paper shredder. The shreds represent viral RNA amplified by Cas13 through “collateral cleavage” and also fluorescent reporters added to the sample responsible for signaling whether or not the Cas13 has found its viral target. This technology is useful in detecting infectious agents, such as Zika or even SARS-CoV-2 because they are usually present in low levels in human samples.
