Answer the following questions:
1. An important difference between Aequorin and GFP is that:
a.
It binds to actin
b.
It is found in large amounts in jellyfish
c.
It has a cofactor
d. It has the fluorescent compound coded within the amino acid sequence
Dr. Shimomura was awarded the Nobel Prize for his work because it has helped advanced biological imaging technology. His research:
Designed synthetic illuminating chemicals based on theories of chemical structural properties
Studied natural chemicals in animals that evolved bioluminescence over billions of years
Was funded because it promised to help cure cancer
Was successful because it didn't take much time in the lab and didn't smell bad
3.
Dr. Shimomura's research could not have been done today because
The jelly fish population is very low
Environmental regulation would not allow it
The nuclear bombs today are way more powerful than in WWII
He would never get a visa to come from a war torn country
Explanation / Answer
1 C
Aequorin is a protein that was purified from the jellyfish, Aequoria victoria, which emits light upon binding to its cofactor coelenterazine and calcium.
Unlike other bioluminescent reporters, the chromophore in GFP is intrinsic to the primary structure of the protein, and GFPfluorescence does not require a substrate orcofactor.
2 B Studied natural chemicals in animals that evolved bioluminescence over billions of years
3 B Environmental Regulation won't allow it
