Site directed mutagenesis is used to: 1.determine the critical base per sequences in a Genome 2. Create genomic libraries 3. Determine the critical amino acids in a protein that allowed to function 4. Amplify dna 5. sequence dna

CRISPR/Cas9 mediated genome editing has provided an unparalleled means of manipulating the genome. Describe in 2 sentences/lines maximum what three requirements must be met in order to target a specific dsDNA break at a given site in genome of the target organism using this system?

3). Explain a substitution mutation 4) Explain a deletion mutation 5). Explain an insertion mutation

A patient is diagnosed with lung cancer using imaging. To establish the best treatment option, doctors ask to profile the gene expression of the tumor, using a biopsy and microarray analysis. Describe the steps involved in the analysis in detail. The analysis reveals that a new gene therapy could be beneficial to the patient. Explain briefly how gene therapy could be used to cure cancer and detail how the treatment can be formulated for delivery to the patient. To prepare DNA for the gene therapy formulation, it is often important to measure the size of the molecule. Explain how this measurement can be done using agarose gel electrophoresis, taking care to detail the property of the DNA molecule at the basis of the technique. To generate large amounts of DNA to manufacture gene therapy payloads or to be able to see them on gel electrophoresis, specific sequences can be amplified by PCR. For a sequence of a 100 base pairs, calculate the number cycles of PCR required to generate 1 ng of…

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. CRISPR technology Specialized stretches of DNA with nucleotide repeats and Cas9 protein spacers Enzyme that cuts DNA crRNA Guides the enzyme to the target site CRISPR DNA Adapted from the natural defense mechanism of bacteria and archaea
