Learning Path
Question & Answer
Choose the Best Answer
By using RNA to guide the Cas9 enzyme to specific DNA sequences
By randomly inserting DNA fragments into the genome
By permanently altering the cellular structure of the nucleus
By replicating the entire genome before making edits
Understanding the Answer
Let's break down why this is correct
CRISPR uses a short RNA guide that matches a DNA sequence. Other options are incorrect because Some think CRISPR drops DNA pieces everywhere; People may think CRISPR changes the shape of the nucleus.
