What is DNA? A molecule that carries the genetic instructions for life A type of fat A type of protein A kind of sugar

Did you know that DNA, or deoxyribonucleic acid, was first discovered in the late 19th century? However, it wasn't until 1953, when James Watson and Francis Crick proposed the double helix structure, that scientists truly understood how this incredible molecule works. The discovery was so groundbreaking that it earned them a Nobel Prize, along with Rosalind Franklin, whose x-ray diffraction images were pivotal! In real-world applications, DNA is the star of modern genetics and biotechnology! From solving crimes through DNA fingerprinting to identifying genetic disorders and even developing personalized medicine, the uses are endless. Scientists are also using DNA in debates around genetically modified organisms (GMOs), ensuring we're well-informed about the foods we eat. Talk about a molecule that makes a difference!
