TED-Ed: The twisting tale of DNA - Judith Hauck

The video explains how diverse organisms, from elephants to mushrooms, share a common mechanism for determining form and function through DNA. DNA, a simple double molecule, stores genetic information in sequences of nucleotides. These sequences dictate the differences between species. DNA acts as a library of information, directing protein synthesis, which is crucial for cell function and reproduction. Genes, segments of DNA, are responsible for producing specific proteins like insulin. Genetic variations and mutations, though rare, can lead to evolutionary changes over time.
