A transgene is a gene or genetic material that has been transferred naturally, or by any of a number of genetic engineering techniques from one organism to another. The introduction of a transgene (called "transgenesis") has the potential to change the phenotype of an organism.
Pharmaceuticals Molecular genetics is scientific study of composition of genes. This field is a subcategory of biology and heredity which is responsible for unearthing and delving the anatomy and physiology of the genes. This field helps us to understand and find evidence in the compounds, substances and elements found and synthesized in our genes and what contains in our nucleic acids –RNA and DNA –framework of our chromosomes. And also the origin and history of how genes came to be. These are codes and like-signals that makes us who we are in a macro-perspective.
I'm inclined to think that the answer is A. These are products, so they can't really be reactants (unless the equation is reversible, which this is not). Cellular respiration is the process of the cells releasing the waste that they do not need. So A seems to be the logical choice.
