In addition, when proteins are being made, the double helix unwinds to allow a single strand of DNA to serve as a template. This template strand is then transcribed into mRNA, which is a molecule that conveys vital instructions to the cell's protein-making machinery.
Best Answer: In organisms: DNA is double stranded. RNA is single stranded (though sometimes folded back on itself, as in tRNA). DNA is found in the nucleus (in eukaryotes) or free-floating in the cytoplasm (in prokaryotes), RNA is found pretty much anywhere, depending on the type of RNA. In viruses: DNA can be double or single stranded.
