Differences:

- DNA is double-stranded, RNA is single-stranded.

- DNA contains a pentose sugar Deoxyribose, RNA contains the pentose sugar Ribose. A pentose is a 5-carbon sugar molecule.

- DNA is limited to the nucleus, RNA is made in the nucleus, but can travel outside of it.

- DNA has a nitrogenous base called Thymine, but RNA doesn't. Instead, RNA has Uracil. In DNA thymine pairs with adenine, but in RNA uracil pairs with adenine.

- There is only one type of DNA but 3 kinds of RNA (messenger, transfer and ribosomal RNA)
