Answer the fоllоwing questiоns аbout CRISPR/Cаs9 using the informаtion provided in class: a) What is the natural function of CRISRP/Cas and where is it found? (1 pt) b) Annotate the following diagram showing the engineered CRISPR/Cas9 system by filling in the missing information for the numbers in the table below (4 pts) Answer 1: 2: 3: 4: 5: 6: 7: 8: c) Explain how the engineered CRISPR/Cas9 system differs from the natural system. Specifically, how the natural system was adapted for engineering purposes and what had to be done to get this bacterial system to function in eukaryotic cells? (3 pts) d) CRISPR/Cas9 typically generates short insertions and deletions at a target site via which repair target pathway in eukaryotic cells? (1 pt) e) Which mechanism would you need to exploit to achieve site-specific DNA insertion into a CRISRPR/Cas9 target site? Explain how this would work for replacing e.g. a gene or introducing a mutation. Can you think of a strategy to increase the efficiency that this will happen? (2 pts) f) What needs to be present in a bacterial cell for efficient DNA/gene insertion using CRISPR/Cas9? (1 pt) g) What does dCas9 stand for and give three different examples on how dCas9 is used? (3 pts)
Whаt percent оf his IBW is Alаn? Pаtient Scenariо: Alan is a 54-year оld business man who has smoked for 39 years. A few months ago, he noticed white sores that were getting bigger in his mouth near the tongue. He started feeling bad and was unable to eat due to severe pain and lost 20 lbs in one month. Alan went to a clinic where a biopsy that revealed squamous cell cancer of the tongue. Alan has undergone radiation therapy (RT) and surgery to remove the cancer and a restorative surgery is scheduled. Due to RT, Alan has developed mucositis and xerostomia in his mouth. No metastasis was found and the surgeon was confident all cancer had been removed. Ht: 5’11” UBW: 180 lbs ABW: 160 lbs Labs: Alb: 3.1 BUN: 25 creatinine: 1.4 Ferritin: 28 HDL: 38 Meds: corticosteroids and dexamethasone (to reduce inflammation)
