What Is the Difference Between DNA and RNA? | Britannica
WebDNA is composed of long strands of the nucleotides adenine, guanine, cytosine, and thymine. In RNA, the thymine is replaced by uracil. The order and patterns of these nucleotides form the genetic code. Physically, DNA is structured as a double helix, with two strands of DNA winding around each other, while RNA is structured as a single strand.
