What are the three main differences between a molecule of DNA and RNA?

Firstly, we can see a difference in the letters, DNA has a D whereas RNA has an R, when we think about the full names we come to deoxyribose and ribose, which correspond to the different sugar molecules found in these structures Secondly, if we think of the general structure we realise that DNA is double stranded whereas RNA consists of only one strand Thirdly, we can think of the bases that make up DNA and RNA. DNA consists of Thymine, Adenine, Guanine and Cytosine, whereas in RNA Uracil replaces Thymine
