What is CRISPR?

What does CRISPR stand for?

• Clustered Regularly Interspaced Short Palindromic Repeats

• Complementary RNA Isolated from Spacer DNA

• Cytosine Ribonucleotide Inhibiting Spacer Protein Replication

• Cas9 RNA Interfering with Spacer DNA

What are the two main parts found in CRISPR?

• Repeats and Spacer DNA

• Repeats and Viral DNA

• Spacer DNA and Cas Proteins

• Cas Proteins and Viral DNA

What is the function of the cas genes in CRISPR?

• They produce cas proteins that unwind and cut DNA

• They produce cas proteins that repair damaged DNA

• They produce cas proteins that replicate viral DNA

• They produce cas proteins that prevent DNA transcription

How does the CRISPR system help bacteria fight viral infections?

• It breaks apart viral DNA and prevents infection

• It embeds viral DNA into the bacterial genome

• It produces antibodies to neutralize viral DNA

• It triggers white blood cells to attack viral DNA

What is the role of the Cas9 protein in the CRISPR-Cas9 system?

• It cuts DNA at specific locations

• It repairs damaged DNA

• It replicates viral DNA

• It prevents viral DNA transcription

What is the purpose of the guide RNA in the CRISPR-Cas9 system?

• To provide the sequence information for DNA cutting

• To repair damaged DNA

• To replicate viral DNA

• To prevent viral DNA transcription

How does the CRISPR-Cas9 system inactivate a gene?

• By cutting the DNA at specific locations

• By repairing the damaged DNA

• By replicating the viral DNA

• By preventing the DNA transcription

What can be done using the CRISPR-Cas9 system in living cells?

• Fixing genes in individuals with genetic disorders

• Creating new embryos with desired genetic traits

• Preventing viral infections in bacteria

• Producing antibodies to fight diseases

What is the potential application of CRISPR-Cas9 in treating cystic fibrosis?

• Fixing the genes associated with cystic fibrosis

• Preventing viral infections in individuals with cystic fibrosis

• Creating new embryos without the cystic fibrosis gene

• Producing antibodies to alleviate cystic fibrosis symptoms

How does the CRISPR-Cas9 system differ from the immune system in humans?

• CRISPR-Cas9 system uses RNA to guide DNA cutting, while the immune system uses antibodies

• CRISPR-Cas9 system repairs damaged DNA, while the immune system fights infections

• CRISPR-Cas9 system prevents viral DNA transcription, while the immune system produces antibodies

• CRISPR-Cas9 system replicates viral DNA, while the immune system attacks viral DNA
