You are hired as a senior research associate at a biotech company

I was wondering if you would be able to answer these two questions for me. I am extremely confused. The first question is.1. You are hired as a senior research associate at a biotech company. Your first task is to identify deferentially expressed genes in two strains of chimpanzee. You have a choice between 2D-differential gel electrophoresis and Nucleic Acid-Programmable Protein Array. Identify the method that you will use. Explain the underlying principle of the method you chose and justify why it is the method of choice for this task? –> can you please answer it with both techniques. For example, why 2D- gel electrophoresis and explain the principle of the method and why is this the method of choice for the task and then another answer as to why Nucleic Acid-Programmable Protein Array method and also explain the principle of the method and why this would be the method of choice for the task. Would that be okay with you?the other question is2. Compare and contrast two approaches used to study protein-protein interactions.
