GM is a special set of technologies that alter the genetic makeup of organisms such as animals, plants, or bacteria. Biotechnology, a more general term, refers to using organisms or their components, such as enzymes, to make products that include wine, cheese, beer, and yogurt. Combining genes from different organisms is known as recombinant DNA technology, and the resulting organism is said to be “genetically modified,” “genetically engineered,” or “transgenic.” GM products (current or those in development) include medicines and vaccines, foods and food ingredients, feeds, and fibers. Locating genes for important traits—such as those conferring insect resistance or desired nutrients—is one of the most limiting steps in the process. However, genome sequencing and discovery programs for hundreds of organisms are generating detailed maps along with data-analyzing technologies to understand and use them.

Here come the questions: What Makes an Animal an Animal? just DNA?

Well in most cases, when you’re eating meat you don’t usually eat the whole animal. You eat just a part of it instead. So the definition of animal doesn’t really matter to me in this case. But the question is, does dna count as a part of it or not?
For instance, a strict vegan, doesn’t have any animal products including milk and egg. Is it okay for them to just have the dna of the animals but not any product from animals?
