What does "modern biotechnology" refer to in the context of genetically modified organisms?

"Modern biotechnology" in the context of genetically modified organisms encompasses advanced techniques that involve nucleic acid manipulation and cell fusion across different species or taxonomic families. This includes methods such as recombinant DNA technology, where DNA from one organism is inserted into another organism, and various techniques for gene editing, such as CRISPR.

The reason this option is correct is that it highlights the significant advancements in biotechnology that allow for more precise and targeted modifications to an organism’s genetic material, which can enhance traits such as disease resistance or nutritional value beyond what traditional breeding could achieve. This broad scope distinguishes modern biotechnology from more traditional or limited approaches, which are defined by their constraints on species compatibility and genetic manipulation techniques.

The other choices limit the concept of biotechnology either to traditional methods, which do not incorporate the sophisticated molecular techniques characteristic of modern practices, or to cell fusion within a single species, which again falls short of the potential and breadth of cross-species capabilities that typify modern biotechnology. The scope and technological foundation present in the correct answer truly define the field of modern biotechnology as it relates to genetically modified organisms.
