Answer:
The initial step of producing protein in a pig kidney artificially may involve the study of number mRNA produced by kidney.
Explanation:
As the protein is produced mainly in the kidney by studying the mRNA produced in it. It shows the locations of kidney elevated proteins such as the – proximal tubules, glomeruli etc. The maximum amount of proteins is seen in the genes, present in the kidney. 
The whole system of kidney shows that the gene expression is shared mostly with the liver.  So while producing the artificial protein in pig kidney, the number of mRNA should be considered.
