<span> Both of them are nucleic acids. And that is about the only similarity they share. ;)

One of the major differences between the two is that DNA is double-stranded and RNA is single stranded. Also, DNA contains the nucleotide T whereas RNA contains U.

RNA copies the genetic information found within DNA and uses it to assemble protein, as well as ribosomes. Hence, RNA is a crucial part in protein synthesis, being directly involved in it, whereas DNA is indirectly involved in this process.

There are three types of RNA: mRNA (messenger RNA), rRNA (ribosomal RNA) and tRNA (transfer RNA). As far as DNA is concerned, there is only one type of DNA. ;) Another difference.

Also, in some viruses the RNA replaces the DNA but the DNA will never replace the RNA. Yet another difference. </span>
