| A | B |
| Gene | piece of DNA that codes for a particular protein |
| Protein synthesis | building amino acids into proteins |
| Nucleotide | consists of sugar, phosphate, & base |
| Double helix | shape of DNA molecule |
| Codon | mRNA base triplet |
| Base Pairing | Adenosine goes to Thymine as Cytosine goes to Guanine |
| Mutation | sudden genetic change |
| Amino Acids | Building blocks of protein |
| Uracil | base substitute for Thymine in RNA |
| Deoxyribose | 5 Carbon sugar in DNA |
| Ribose | 5 Carbon sugar in RNA |
| Adenosine/Guanine | Purine bases |
| Cytosine/Thymine | Pyrimidine bases |
| Nucleus | location of DNA |
| anticodon | tRNA base triplet |
| 20 | number of amino acids |
| Methionine | "start" codon - AUG |
| Replication | one strand of DNA copied |
| Transcription | the process of mRNA reading the DNA into code |
| Translation | assemblage of amino acids at the ribosome |
| Ribosome | chemical "workbench" where proteins are assembled |
