Step-by-step explanation:
Streptomycin is an antibiotics produced from bacteria and fungi and it is used to treat bacteria infections (prokaryotic ) such as tuberculosis, mycobacterium infection e.t.c.
It's inhibit protein function in prokaryotes because it's affects the function and performance of 70 s RIBOSOMES which is an organelles for protein production.
Streptomycin does not affect eukaryotes because it does not bind to the RIBOSOMES of eukaryotic cells which in turn does not affect protein production.
