Vaccination program have been successful against many infectious diseases that once killed, crippled, or incapacitated large number of members of a population.
Answer:
C. Diabetics will have ample supplies of insulin that are produced by bacteria.
Explanation:
The technology of recombinant DNA has allowed scientists to introduce the human insulin gene into E.coli bacteria. E. coli are thus turned into "biological factories" that produce large quantities of human insulin, which can be easily purified and used as medicine for diabetics.
There are many more examples of DNA recombinant technology in human medicine, such as the production of recombinant human growth hormone (hGH) also in E. coli that is injected in individuals who don't produce enough hGH naturally, or even the production of vaccines by inserting antigen-coding DNA into a cell, purifying it and later injecting it into individuals to stimulate immunization.
