For the first modified gene sample, they observe that the intron is no longer being spliced out. Which of the lettered arrowheads indicates a location where this insertion could be? (There could be one answer or several. Give all answers that apply)

If the researchers carry out a PCR for this gene from the CD8+ T cells, what result would you expect?Explain.

To determine if the antibiotic resistance in MH1 was carried on a plasmid, you first isolate the plasmid in MH1 using the plasmid DNA purification technique. Then, you transform bacteria that are not resistant to penicillin/ampicillin with the plasmid isolated from MH1. For the bacterial transformation experiment, you set up the three controls listed below. Match each control with its appropriate purpose (i.e. what it is controlling for) Please note: Transformed bacteria are bacteria that received the plasmid from MH1 and untransformed bacteria are bacteria that did not receive a plasmid. Testing to ensure that the bacteria used in the transformation experiment are viable (i.e. can grow on LB media) (Choose) [ Choose ) after transformation. Untransformed bacteria plated on LB only plate Testing to ensure that the bacteria used in the transformation experiment are viable (ie. can grow on LB media) before transformation. Transformed bacteria plated on LB only plate Untransformed bacteria…

You are employed in a gene therapy laboratory to test the effectiveness of a vector for correcting the DF508 –CFTR mutation.  The vector uses CRISPR –CAS9 genome editing to correct the mutated gene in situ (CFTR-CRISPR). An Ussing chamber experiment was performed using nasal airway cells obtained from a patient with the DF508 CFTR mutation which were transformed with either a control vector consisting of an inert CRISPR-CAS-9 construct (CONTROL) or the active, gene correcting CRISPR CAS-9 construct (CFTR-CRISPR).  The following transepithelial voltage values were obtained for the drug regimen shown under open circuit and current clamp (injected current of 10mA) conditions: CONTROL   Baseline Amiloride Forskolin Inh172 Vte (mV) -78 -2 -4 -3 DVRt (mV) 8 16 7.5 13 R (W.cm-2) 800 1600 750 1300 I (mA.cm-2) 98 1 5 2 CFTR-CRISPR Vte (mV) -38 -6 -23 -9 DVRt (mV) 9 27 6 11 R (W.cm-2) 900 2700 600…

In the practical you have been analysing a human genomic library. You know from your calculations that only a small proportion of the human genome is represented, even when the entire class results are considered. Therefore, the chance of finding a particular single-copy gene in your library is very small. Outline a strategy for constructing a genomic DNA library more representative of the entire human genome. You will need to consider alternative vectors and the efficiency of transformation of the bacterial cells.
