Ribonucleic acid interference (RNAi) is effective in the treatment of cancer patients. Harnessing these molecules to silence genes involved in the development and growth of cancer cells is an important step forward in developing a new and more targeted type of cancer therapy.

which of the following could be an effective method to
suppress tumor growth in a patient? (Select all that
apply)
C. Developing cancer reagents that promote insulin signaling to the cell would be beneficial because it would inhibit the cell's ability to take in glucose B. Developing cancer reagents that promote the TCA cycle would be beneficial because it could diminish the Walberg effect O D. Developing cancer reagents that inhibit pyruvate kinase would be beneficial because it inhibits glycolysis...

please answer all that you can 1. You have genetically engineered green fluorescent protein (GFP) containing a KDEL sequence (GFP-KDEL). When GFP-KDEL is expressed in normal human fibroblasts and examined using fluorescence microscopy, the fluorescence appears diffuse across the cytoplasm. How would you explain this observations given that KDEL is supposed to be an ER-specific sorting sequence? A. This engineered GFP would not have a hydrophobic signal sequence to get it into the RER in the first place. B. The...
