Recombinant DNA technology developed during
A. The 1970s
B. The 1980s
C. The 1990s
D. The 2000s

Hint: By the Encyclopedia Britannica, the Recombinant DNA Technology kind of generally is defined as "the joining together of DNA molecules from different organisms and inserting it into a host organism to particularly definitely produce new genetic combinations that are of value to science, medicine, agriculture and industry" in a subtle way.

Complete answer:
Recombinant DNA technology was first applied to protein production in mammalian cells in the early 1980s in a big way. This approach particularly was facilitated by the development of transfection methods for the efficient delivery of plasmid DNA into cultivated mammalian cells. There generally are two main approaches, kind of stable gene expression and transient gene expression, to produce recombinant proteins in mammalian cells, or so they essentially thought. SGE refers to the fact that the foreign gene is stably integrated into the host cell genome, actually contrary to popular belief. The recombinant protein generally is usually constitutively expressed as the cell is cultivated, but it mostly is also for all intents and purposes possible to put the transgene under the control of an inducible promoter so that its expression can really be temporally regulated, or so they thought.

Hence the correct answer is option B. Recombinant DNA technology developed during the 1980s.

Note: Recombinant DNA technology refers to the joining together of DNA molecules from two different species that mostly are inserted into a host organism to generally produce new genetic combinations that for the most part are of value to science, medicine, agriculture, and industry, for all intents and purposes contrary to popular belief.
