Genetically Modified Organisms (GMO) Bacteria were the first to be used for insulin production. In the 1970s, scientists successfully introduced the human insulin gene into bacteria like Escherichia coli (E. coli), allowing these bacteria to produce insulin in large quantities. This breakthrough revolutionized diabetes treatment, making insulin widely available.
Step 1: Analyze the options.
(A) Plasmodium: Plasmodium is the genus of parasites that causes malaria and is not related to insulin production.
(B) Eisenia fetida: This is a species of earthworm, and while it has various uses in agriculture and ecology, it is not used for insulin production.
(C) GMO Bacteria: This is the correct answer. Genetically modified bacteria, like E. coli, were used to produce insulin after the gene for human insulin was introduced into them.
(D) Fungi: Fungi have been used in biotechnology, but they were not the first to be used for insulin production. GMO bacteria were the breakthrough in this area.
Step 2: Conclusion.
The correct answer is (C) as genetically modified bacteria were the first used for insulin production.
Final Answer:
