Chalkboard rounds

What is CRISPR?

A guide finds a matching DNA sequence; a tool cuts it, and researchers check what changed.

Chalkboard titled What is CRISPR? showing three DNA diagrams labeled Guide, Cut, Edit, with a guide RNA, scissors, and an edited DNA sequence. Text reads A tool to edit DNA.
Guide, cut, edit is a simplified explanation. Finding a target does not guarantee the intended edit or a safe treatment.

See the early clinical example in Dr. Mohan's CTX310 Reading Room note. The 15-person first-in-human trial does not yet show whether the treatment prevents heart attacks.
