Crispr

What does the guide RNA do?

• destroy invaders like bacteriophages immediately

• cut invading pieces of RNA

• recognize invaders

• recognize sequences of DNA to be edited.

What is the role of gRNA? (gRNA -> guide RNA)

• the cell recognizes that DNA is damaged and tries to repair it

• ensures that the Cas9 enzyme cuts at the right point in the genome

• use the DNA repair machinery to introduce changes to one or more genes

• makes a cut across both strands of the DNA

Scientists have adapted it to turn it into a biotechnology tool for _______ DNA.

• building

• editing

• destroying

• synthesizing

CRISPR-Cas9 was discovered in which of the following organisms?

• protists

• fungi

• bacteria

• viruses

What is the definition of genetic engineering?

• Studying the DNA of plants and animals

• Making changes in the DNA code of living organisms

• The discovery of DNA Using DNA to reproduce organisms

• Using DNA to reproduce organisms

How does the guide RNA help the cell know where to cut the DNA?

• Guide RNA helps to find the PAM

• Guide RNA is complementary to the DNA sequence

• Guide RNA always binds to the same sequence of DNA

• Like restriction sites, they are always palindromes

What does CRISPR stand for?

• Clustered regularly interactive short palindromic repeats

• Clustered regularly interspaced short palindromic repeats

• Deoxyribonucleic acid

• Regularly interspaced short palindromic repeats
