How is recombinant DNA defined?

• A. DNA that is inherited from ancestors
• B. DNA that is formed artificially by combining constituents from different organisms
• C. DNA that is read by RNA polymerase
• D. DNA that solely exists in bacteria

Answer: (B)

Recombinant DNA is defined as DNA that is formed artificially by combining constituents from different organisms. This process involves taking DNA segments from two or more sources and combining them so that they can replicate and express in a new host organism. The significance of recombinant DNA technology lies in its ability to harness the genetic material of various organisms, allowing for the production of proteins with desired traits, the creation of genetically modified organisms, and advancements in medical therapies. In contrast, DNA inherited from ancestors refers to the natural transmission of genetic material through generations, which does not involve the artificial manipulation seen in recombinant DNA. The reading of DNA by RNA polymerase pertains to transcription and the processes of gene expression, which is not specific to recombinant DNA. Lastly, although bacteria can utilize recombinant DNA techniques, it is not exclusive to them; recombinant DNA can exist in many other organisms and cell types, demonstrating that it is a broader concept than simply being found in bacteria. Thus, the defining characteristic of recombinant DNA is its artificial synthesis from multiple sources.
