CRISPR in Agriculture

What is CRISPR? (select 3)

• An abbreviation for clustered regularly interspaced short palindromic repeats

• A gene editing tool

• A naturally occurring process that defends bacteria against viruses

• A restriction enzyme

When viruses infect bacteria, CAS proteins cut out a segment of their DNA and makes RNA copies. Generally, how many nucleotides do these copies have?

• 15

• 30

• 20

• 25

The development of CRIPSR is important to agriculture because ​​it uses (a)   to modify crops.

• a variation of DNA from the crop itself
• foreign DNA
• DNA from a different crop in a nearby area
• human DNA

In chronological order, reorder the blocks to state the procedure for CRISPR gene editing in a lab.

• Design a single-guide RNA that matches the gene you want to edit

• Attach the single-guide RNA to enzyme CAS9

• The single-guide RNA directs CAS9 to the targeted gene you want to edit

• CAS9 cuts the targeted segment of DNA

• A natural repair mechanism initiates, and either non-homologous end joining or homology-directed repair occur

What have scientists used CRISPR gene editing for in agriculture? (select 4)

• To make crops more resistant to threats within their environment

• To duplicate crops

• To improve crop yield

• To allow crops to last longer after they are harvested

• To speed up crop growth

Why is CRISPR considered to be non-GMO?

• It inserts foreign DNA

• It uses GM techniques
