- Although CRISPR uses some of the same viral vectors as "gene therapy," which was pioneered in the 1990s the cargo is more targeted. True FalseThis is a multiple answers question. Which statement is true about CRISPR-Cas system? CRISPRS stand for clustered regularly interspaced short palindromic repeats Both bacteria and archaea can protect themselves from viral infection by using this system. Cas protein and short RNA form a complex The CRISPR region of DNA contains DNAS from previous infection by phages. Cas protein cuts target foreign DNA in pieces. The short RNA in the Cas protein and RNA complex has no function.Label the following parts of the CRISPR-Cas 9 system. C A B C D Target DNA strand PAM sequence Cas9 protein Single-guide RNA
- Bacteria exposed to viruses incorporate sections of the virus’s DNA into the CRISPR array sequences in their genome. This mechanism allows bacteria to fight off the viruses, like an immune response: the information in CRISPR spacers served as “coordinates” for recognizing and cutting up invading DNA sequences. Describe what might happen under the conditions described after a bacteriophage infects a bacterial cell and releases its DNA into the bacterial cell. Explain why: The cas genes on the bacterial genome contains a frameshift deletion mutation that alters the function of the protein The bacteria will be unable to elicit an immune response and will succumb to the phase infectionBriefly compare (a) restriction enzymes, (b) engineered nucleases and (c) CRISPR-Cas in terms of their origin, nature, and mechanism.Bacteria exposed to viruses incorporate sections of the virus’s DNA into the CRISPR array sequences in their genome. This mechanism allows bacteria to fight off the viruses, like an immune response: the information in CRISPR spacers served as “coordinates” for recognizing and cutting up invading DNA sequences. Describe what might happen under the conditions described after a bacteriophage infects a bacterial cell and releases its DNA into the bacterial cell. Explain why: 1. The invading phage DNA is recognized by the Cas proteins but not inserted into the CRISPR array region of the bacterial genome: The bacteria will be unable to elicit an immune response and will succumb to the phase infection 2. The cas genes on the bacterial genome contains a missense mutation that increases its cleavage/cut activityThe bacteria will elicit an immune response that will successfully fight the phage infection
- Cloning vectors are not just limited to bacterial plasmids. Bacteriophages and M13 phage vectors are also commonly utilized in the cloning process. State any five (5) key criteria to be an effective cloning vector.With reference to the image below, discuss the process and principle involved for screening/selection of hosts (last stage of cloning) containing the intended recombinant plasmid. LacZ' = Gene for alpha-peptide of β-galactosidase.Which of the following types of mutations would be produced by repair of a CRISPR-targeted double stranded break through non-homologous end joining? acquisition of a point mutation specified on a donor DNA template deletion duplication inversion
- Genetically modified Atlantic salmon have recently been approved for human consumption. These genetically modified Atlantic salmon have a growth hormone gene from the Chinook salmon which allows them to grow to market size in double the time. This was possible because of CRISPR/Cas9 technology. From what you know about gene editing and CRISPR/Cas9, name 2 components of the technology that had to be introduced into the Atlantic salmon. Which method of DNA repair had to be used (non-homologous end joining or homology‐directed repair) to edit the Atlantic salmon genome?CRISPR One of the more recent advances in biotechnology is the development of the CRISPR gene modification tool. Match the following descriptions the the key players in this technology. NOTE: If you want to change your selection, you'll need to delete the one you already chose. After you delete it, the list of choices will pop back up and you can make a different choice.
