Which of the following statements is not true about the guide RNA (see this interactive demonstration for help with this question: https://www.biointeractive.org/classroom-resources/crispr-cas9-mechanism-applications) Group of answer choices it contains a sequence of 20 nucleotides that matches a specific sequence in a cell’s DNA When the guide RNA is combined with Cas9, it will guide Cas9 to the target sequence its target sequence can be almost any sequence as long as it occurs near a PAM motif it is a nuclease, a type of enzyme that cleaves DNA
CRISPR-cas9 is a powerful technique for gene editing. Please place the stages of a CRISPR-cas9 gene editing workflow in the correct order from stages 1-9. Note, there is one incorrect, redundant answer. - Add green fluorescent protein gene sequence into plasmid to aid selection of correctly transfected cells.- Clonal characterisation (analysis of phenotype).- Synthesize DNA insert oligonucleotides.- Select for correctly gene edited cells (using antibiotic resistance and/or color production for example).- Transfect cells- Purify plasmids- Clone into CRISPR-cas9 expression vector.- Design a set of targeting sequences using algorithms.- Clonal isolation.- Sequence.

A number of advances have been made in biotechnology. CRISPR/Cas9 one of the most controversial, and has had a lot of media attention in recent years. It is a method by which scientists can precisely edit DNA sequences at exact locations. Benefits obviously include the potential to “repair” mutated genes that cause disease. In fact, preliminary results from one of the earliest clinical trials of CRISPR/Cas9 provide evidence that the technique is safe and feasible to use for treating human diseases. What other potential applications of this application do you see (you can use any organisms to illustrate your answer)? What are the potential dangers or downsides of using this technology? Do you think this technology should be used in gene editing in humans? Explain your stance.

During experimental RNAi, how does the researcher affect expression of a target gene? Group of answer choices Inject custom, lab-made double-stranded RNA into the specimen that will be targeted by the cell's existing Dicer to create siRNA complementary to the target gene's transcript. Inject lab-made Dicer proteins into the specimen which will cut up the target gene's transcript. Inject custom, lab-made siRNAs complementary to the target gene's transcript.
What are the major components of the CRISPR-Cas9 system? What mechanism does it employ to combine DNA? Explain the process of how the CRISP-Cas9 system is able to create recombinant DNA. Relate the idea of gene modification to the fields of vaccines and applied microbiology as well.
One concern about using genetically-modified organisms is that many of the methods used to create them introduce into the genome DNA from a different species (i.e. foreign DNA). Which of the following methods has the lowest potential of introducing foreign DNA into the genome?A. A gene knockout in mouse using homologous recombination in ES cellsB. Introduction of a P element vector into the Drosophila germ-lineC. Deletion mutations introduced by CRISPR/Cas9D. Microinjection of a transgene into a mouse pronucleus
