MAKE CONNECTIONS In Concept 20.2, you learnedabout genome-wide association studies. Explain howthese studies use the systems biology approach.
Q5. a) Imagine you are a scientist in Wuhan in late 2019 and you have just sequenced thepathogen that is spreading rapidly, killing people due to pneumonia. How will you investigate theorigin of the pathogen?b) How will you use the sequence to guide vaccine discovery or drug development againstCOVID-19? (Hint: You can block the entry of virus, stop the virus from replicating in cells orlower the disease caused by the virus)
