| DNA is a kind of nucleic acid and is made up of nucleotides. RNA is built up of nucleotides that contain phosphate, sugar, and a nitrogen base. | |

| You make it sound like DNA and RNA are the same thing, are they? | |

|
| | |
| NO, NO, NO! DNA has a deoxyribonucleic acid and RNA has a ribonucleic acid. RNA also has a ribose sugar while DNA has a deoxyribose sugar. | |

| Oh! And doesn't RNA contain a nitrogeneous base called Uracil, instead of thymine in DNA? | |
