Answer:
d. a bacterium with human gene for producing insulin
Explanation:
Transgenic organisms are the organisms in which the foreign DNA is introduced by using the molecular techniques for obtaining a particular result. This foreign DNA can be introduced using a vector called plasmid vector.
One of the examples of transgenic organisms is E.coli with the human gene for producing insulin. So for producing artificial insulin, the gene which produces insulin peptide is ligated in a plasmid vector and then this plasmid is introduced in the bacterium where this plasmid replicates and produces insulin. So the correct answer is d.
The kidney is involved in several processes, but its main function is to ensure the detoxification of the body by removing waste by urine. It filters the blood plasma and ensures homeostasis (balance of water and ions) of the body.
In kidney damage, the kidney indeed loses its function, and the level of all metabolites that are supposed to be eliminated by the kidney increase in the blood, like urea, ammonia, and uric acid.
