    About the Lecture

    The lecture CRISPR-Cas9 System by Georgina Cornwall, PhD is from the course Biotechnology.


    Included Quiz Questions

    1. A family of DNA sequences containing pieces of DNA from invading viruses that attack the host bacterium
    2. A family of RNA sequences containing pieces of RNA from invading viruses that attack the host bacterium
    3. A family of signal protein sequences containing pieces of antigen proteins from invading viruses that attack the host bacterium
    4. A family of signal lipoprotein sequences containing pieces of immunogenic proteins from invading viruses that attack the host bacterium
    5. A family of signal glycoprotein sequences containing pieces of immunogenic proteins from invading viruses that attack the host bacterium
    1. CRISPR/Cas 9 system helps in the amplification of viral DNA inside the host cells by providing the adaptive immunity to the incoming virus
    2. The viral snippets in the CRISPR of a bacterium play a crucial role in bacterial defense system against the bacteriophages
    3. The pre-designed sequence of the Guide RNA (gRNA) directs the Cas9 nuclease to the right part of the invading DNA molecule for chopping down it
    4. Cas9 nuclease cleaves a double-stranded DNA at specific sites and leads to activation of DSB repair machinery in the bacterial cells
    5. CRISPR/Cas9 system can be used as a targeted genome editing tool in the molecular biology protocols
