It was revolutionary when it was first isolated from bacteria. Always fascinating to me that it's pretty much the bacterial adaptive immune system. Now it's awesome seeing other scientists dial in the precision of an already game changing advancement.
Sorry for the delayed reply, but I studied in this field as welll, so curious why you thought CRISPR would be associated with viruses over bacteria or even mold/yeast?
well because their whole life cycle is about inserting into dna (although not really as many just keep the dna as seperate plasmids). I would think its proteins would be more specialized to the task but turns out does sorta come from them as the crispr genes originated from bacteriaphages but the bacteria use them to now defend against them.
