I’ve got these two images, not sure what they show. I’ve got an exam on them but we haven’t got the questions yet. Can anyone help with what it shows or any ideas on what the question could be?

Any help would be appreciated
Thank you in advance  Slight Smile

There's a lot unfold from this. Firstly, a protospacer target DNA is a specific sequence of DNA that matches a portion of the DNA from which it was transcribed (for example from a foreign invader like a virus or plasmid).

In the context of CRISPR, protospacers are targeted by Cas proteins to recognize and cleave the foreign DNA. To do this, the Cas protein is guided by a complementary RNA molecule (see the part crRNA-sp2), bind to the target DNA and initiate a sequence-specific cleavage.

Does that make sense so far?
When you like a flower, you just pluck it out.
But when you love a flower, you water it daily.
The one who understands this, understands life.

- That's the difference between I like you and I love you.
