Final answer:
Ethical concerns and disadvantages are major disadvantages of advancements in DNA technology, raising questions about ecological effects, genetic privacy, and impact on future generations.
Step-by-step explanation:
A disadvantage of advancements in DNA technology is C) Ethical concerns and disadvantages. These concerns include issues such as privacy, ownership of genetic information, and the safety of genetically modified organisms. Ethical dilemmas also arise from human genetic engineering, such as the impact on biodiversity, potential long-term effects, and the inequality that may result from access to genetic modifications. In the context of gene editing, three important ethical questions to consider are:
- What are the potential long-term ecological effects of releasing genetically engineered organisms into the environment?
- How should we regulate and protect individual genetic information in the face of advancing biotechnological capabilities?
- To what extent should germ-line genetic modifications be pursued, given that they are inheritable and their impacts can shape the human gene pool for future generations?
