Ascientist who has isolated the green fluorescent protein (gfp) gene from a sample of jellyfish dna would use which technology to make gfp protein from the gfp gene most effectively?

To make GFP protein from the GFP gene most effectively is done by combining in the ratios of  4: 2 to make a bunch of copies of the coding DNA, then he pops that coding sequence into an expression vector.
Afterward, he uses that vector to transform the bacteria to make them usable as protein-making factories. The ratio 2 would only make enough DNA's, whereas the ratio 4 will be used to make the protein.

What is your question then

This is the most closely resembles the model.
