Question

read the following text.
diabetes affects over 20 million people in the united states. diabetes can be treated with insulin, a hormone which regulates blood sugar. synthetic insulin can be made using genetically altered microorganisms such as e.coli. this was done by joining the human gene that codes for insulin with a plasmid, a ring of dna in a bacterial cell. the e.coli containing the plasmid can then produce the humanized insulin.
the above text pertains to the subject of ____________.
○ social science
○ humanities
○ biotechnology
○ bacteriology

Explanation:

The text discusses using genetically altered microorganisms (E. coli) to produce human insulin, which is a key aspect of biotechnology. Biotechnology involves using biological systems (like microorganisms) and genetic engineering techniques (joining the human insulin gene with a plasmid) to develop products (synthetic insulin for treating diabetes). Social science focuses on human society and behavior, humanities on human culture (e.g., literature, philosophy), and bacteriology is mainly about bacteria (not the broader application of genetic engineering and biological product development as here).

Answer:

biotechnology
