DNA Structure and Function Explained

The video explains DNA as a polymer made of nucleotides, each consisting of a sugar, phosphate, and base. It details the structure of DNA, highlighting the sugar-phosphate backbone and the four bases: A, T, C, and G. The video covers base pairing rules, where A pairs with T and C pairs with G, and explains how DNA sequences code for proteins by specifying amino acids. The order of bases determines the protein produced by a cell.
