All of the following do not produce a transgenic organism except?
Correct answer: A. Introduction of the desired gene into the organism
- A. Introduction of the desired gene into the organism
- B. Replacement of the nucleus of an unfertilized egg with a diploid nucleus of a somatic cell
- C. Produced from a zygote
- D. Asexual reproduction
Explanation
The correct answer is the introduction of a desired gene into the organism. This method creates transgenic organisms by inserting new genetic material into their DNA to express desired traits. In contrast, the replacement of a nucleus with a somatic cell nucleus, a process used in cloning, does not involve genetic modification to introduce new traits. Similarly, organisms produced from a zygote or through asexual reproduction do not automatically entail the genetic modifications necessary to form transgenic organisms.

About Introduction to Biology
Biology is divided into fields such as botany, zoology, microbiology, genetics, ecology, physiology and biotechnology, each focusing on a different aspect of life. Levels of biological organization progress from atoms and molecules through organelles, cells, tissues, organs and organ systems to organisms, populations, communities, ecosystems and the biosphere.
