a. Describe two ways you could potentially make atransgene that would inhibit the function of a specific gene in a transgenic organism. (Hint: For oneof these techniques, recall the discussion of RNAinterference in Chapter 17.)b. Discuss how you could use either of these methodsto construct a mouse model for a recessive humangenetic condition associated with a loss of function, such as cystic fibrosis.
The ability to selectively modify the genome in the mouse has revolutionized mouse genetics. Outline the procedure for generating a knockout mouse at a specific genetic locus. How can the loxP-Cre system be used to conditionally knock out a gene? What is an important medical application of knockout mice?
Propose some specific uses of a modified CRISPR-Cas system as a general RNA-guided device for altering cellular functions. What might these functions be, and how could CRISPR-Cas be used to study them?

- The following diagram is from a paper investigating the role of β4 integrin in breast cancer. They examined the expression of miRNAs (rows) in ten β4 positive and ten β4 negative breast cancers. Each array was performed in triplicate (columns) (Gerson, 2012). A. Describe how you think this array was carried out. B. β4 integrin is normally involved in attaching epithelial cells to the extracellular matrix and holding them in place, but in cancer, it can be involved in attaching cells to actin and increasing motility as well as in cell signaling. How is β-integrin expression related to miRNA expression? What do you think this means for these breast cancers?arrow_forwarda. What is(are) the difference(s) between orthologs and paralogs? b.

- A graduate student studying yfgA expression in the liver and heart performs an RNA-seq experiment. She aligns her sequencing reads to the human genome as shown. a.) What splice variants are expressed in the liver? Draw the mRNA and label the exons.b.) Are they expressed at the same levels in the liver? Explain c.) What splice variants are expressed in the heart. Clearly explain all the data from the figure. d.) In which tissue is the gene more highly expressed? Explainarrow_forward. One way to determine where inside a cell a protein(protein X) normally localizes is to generate a reportergene construct containing: (i) the gene X regulatoryregion and coding sequences, and (ii) coding sequencesfor GFP fused in frame to the 3′ end of the gene Xcoding sequences just before the stop codon. A mousecontaining such a transgene will express a hybrid protein X-GFP only in those cells in which gene X is normally expressed.a.
