Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA, RNA is found in nature as a single strand folded onto itself, rather than a paired double strand .Does RNA have a helix structure?
The structure of DNA and RNA. DNA is a double helix, while RNA is a single helix. Both have sets of nucleotides that contain genetic information.Is RNA a larger molecule than DNA?
RNA uses the nucleotide uracil instead of thymine. DNA is often 103 to 106 times larger than RNA. RNA is much less stable than DNA. As a single stranded molecule it has no way of reparing itself.
