WH2.12C How CRISPR lets you edit DNA VIDEO

What job does DNA do inside our genes?

• To provide energy for cell processes.

• To act as an instruction manual for our cells.

• To transport nutrients throughout the body.

• To protect cells from external threats.

What is CRISPR in its natural form?

• A synthetic gene-editing tool developed in labs.

• A type of virus that infects bacteria.

• A natural bacterial immune system.

• A protein that builds new DNA sequences.

What are the two main components of naturally occurring CRISPR systems?

• RNA and ribosomes.

• Proteins and lipids.

• Repetitive DNA sequences (CRISPRs) and Cas proteins.

• Mitochondria and chloroplasts.

How do scientists direct Cas9 to a specific gene they want to edit in the lab?

• By exposing the cell to a high-energy laser.

• By designing a guide RNA that matches the target gene.

• By injecting a general enzyme that cuts all DNA.

• By altering the cell's membrane permeability.
