Explanation: CRISPR-Cas9 is most commonly known to be a gene editor, but since its initial discovery, people have found that with some minor tweaks, CRISPR can be made to do a bunch of other things, things that biologists could have only dreamed of previously.

If you introduce a mutation that deactivates the Cas9 protein, the entire CRISPR complex still binds to DNA. Then, you can essentially glue whatever you want onto this modified Cas9 to produce a bunch of different effects:

  • deactivated Cas9, no additional modifications: blocks other proteins from touching the DNA, which suppresses a gene without destroying it
  • glue on some transcriptional activators: makes the cell express a gene
  • glue on some fluorescent proteins: makes your DNA glow, lets you see where it is

Well done! I zoomed in and felt dumb. But thanks to your succinct explanation, I now have a sweet Dunning-Kruger high

I dunno. For hundreds of thousands of years we've been selectively breeding puppies.

In a way one could argue genetic engineering is one of the oldest sciences ever. And it started with dogs, or maybe agriculture, depends on what one's definition of science is.

Sadly there are two spoiler types i know of :/
for me the spoiler works because i use the "second one?"

It's a drawing! It's fiction! And if you come with the "normalizing" argument, then your "Y'all need Jesus" is normalizing the christofascism that will destroy this world.
