| RNA | ribonucleic acid |
| DNA | deoxyribonucleic acid |
| mRNA | single strand of transcribed DNA that can move out of the nucleus |
| rRNA | makes up the ribosome; site of protein synthesis |
| tRNA | carries the anticodon and the amino acid that is coded for |
| sugar, phosphate, nitrogen base | the three parts of a nucleotide |
| A, T, G, C | the four nitrogen bases of DNA |
| A, U, G, C | the four nitrogen bases of RNA |
| Chargaff | scientist who stated that A=T and G=C |

| double helix | the name given to the model of DNA |
| replication | process of uncoiling, unzipping and making an exact copy |
| transcription | process in which DNA makes mRNA |
| translation | process in which mRNA, rRNA and tRNA join together to put amino acids together to make proteins |
| peptide | type of bond used to hold amino acids together |
