What is CRISPR? video Quiz

What does CRISPR stand for?

• Clustered Regularly Interspaced Short Palindromic Repeats

• Cellular Replication and Immune System Protection

• Chromosomal RNA Integration and Splicing Process

• Cytosolic Ribonucleic Inhibition and Synthesis

What are the two main parts found in CRISPR?

• Repeats and Spacers

• Palindromes and Helicases

• Antibodies and White Blood Cells

• Nucleases and RNA

What is the function of spacer DNA in the CRISPR system?

• It creates mutations in the DNA

• It matches up with viral DNA

• It transcribes and translates proteins

• It forms little hairpin turns

What are the cas genes associated with in the CRISPR system?

• They unwind DNA

• They make cas proteins

• They cut the DNA

• They envelop the invader

What is the role of the CRISPR-Cas system in bacteria when a bacteriophage injects its DNA?

• It forms antibodies to fight the viral DNA

• It creates mutations in the viral DNA

• It hijacks the cell and embeds the viral DNA in the genome

• It transcribes and translates proteins to fight the viral DNA

What is the name of the cas protein identified in the CRISPR-Cas9 system?

• Cas5

• Cas7

• Cas3

• Cas9

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

• It has a corresponding bit of RNA to cut the DNA

• It forms antibodies to fight the viral DNA

• It holds the CRISPR RNA in place

• It creates mutations in the DNA

What happens when the DNA is cut by the CRISPR-Cas9 system?

• The gene is inactivated

• The DNA is duplicated

• The DNA is completely removed

• The DNA is repaired without mutations

How can the CRISPR-Cas9 system be used in living cells?

• To produce antibodies against viral DNA

• To fix genes in individuals with genetic disorders

• To create mutations in the DNA

• To remove entire genes from the DNA

What is the main purpose of the CRISPR system in humans?

• To repair damaged DNA in cells

• To produce antibodies against viral DNA

• To fight bacterial infections

• To modify genes and potentially create new embryos
