CRISPR Biology Welcome to your CRISPR Biology quiz. Let's get started. 1. From which bacteria the CRISPR/Cas9 system has been adopted in plant gene editing? S. pyogenes E. coli Bacteriophage None of the above None 2. Any sequence can be used as a target sequence in CRISPR based gene editing. PAM sequence is essential for targeting PAM specific Cas can only be used for gene targeting The statement is false The statement is true Option 1,2 and 3 None 3. Which of the following CRISPR based alteration in DNA is NOT mediated by NHEJ Deletion Insertion Knock out None of the above None 4. What is PCR? Polyprotein complex regulation Polymerase chain reaction Peripheral cell receptor None of the above None 5. What is the function of the guide RNA in CRISPR based gene editing? It guides the Cas9 protein to the target sequence It guides the Cas9 protein to cut the target sequence It helps in the formation of the effector complex It helps in transcription of the Cas9 protein 1 and 2 None 6.
