DNA is a double-stranded molecule that carries genetic information and serves as the blueprint for all living organisms. Its unique structure, discovered by James Watson and Francis Crick in 1953, consists of two complementary strands twisted together in a double helix. DNA plays a crucial role in the transmission of genetic information from one generation to the next, as well as in protein synthesis. Our understanding of genetics and DNA has led to several important breakthroughs in medicine and biotechnology, but it is important to also consider the ethical implications of this knowledge.
