Final answer:
CRISPR/Cas9 is a genome editing tool that is used to make precise changes to the DNA of organisms.
Step-by-step explanation:
CRISPR/Cas9 is a genome editing tool that is used to make precise changes to the DNA of organisms. It works by using the Cas9 enzyme to cut the DNA at specific locations and then allowing the cell's natural DNA repair mechanisms to fix the cut by either inserting a new DNA sequence or deleting a specific sequence.
This technology has revolutionized gene editing and has the potential to cure diseases, improve crops, and even alter the course of evolution.
