| Term | Definition |
| DNA | The double stranded molecule that contains the genetic code |
| TRANSCRIPTION | Process by which DNA is converted to RNA |
| DNA POLYMERASE 3 | Enzyme responsible for replication of DNA; catalyses the addition of bases to the growing strand. |
| OKAZAKI FRAGMENTS | Short strands of DNA created when the 'lagging' DNA strand is replicated |
| THYMINE, ADENINE, CYTOSINE, GUANINE | The four nitrogen containing bases of DNA |
| URACIL | Nitrogen base that appears in RNA but not in DNA |
| RIBOSE | Sugar that appears in RNA molecules |
| DEOXYRIBOSE | Sugar that appears in DNA molecules |
| DNA LIGASE | Enzyme responsible for joining Okazaki fragments |
| EUCHROMATIN | DNA that is being transcribed, a region of DNA that is uncoiled and undergoing active transcription into RNA |
| DNA HELICASE | Enzyme unwinding DNA allowing it to be transcribed |
| TRANSLATION | Process by which RNA is converted into proteins |
| NUCLEUS | Organelle in which DNA is stored in an eukaryotic cell |
| RIBOSOME | Organelle responsible for translation of mRNA to protein |
| RNA POLYMERASE | Enzyme responsible for transcription of mRNA |
| SPLICEOSOME | Enzyme complex responsible for removing introns from pre-mRNA |
| tRNA | Molecule consisting of 75-80 base pairs. Responsible for delivering the amino acid to the ribosome complex |
| WOBBLE | Codon-anticodon interaction that tolerates a mismatch b/w the 3' base of the codon, and the 5' base of the anticodon. |
| POLYPEPTIDE CHAIN (ie: the order of amino acids) | Primary protein structure |
| PEPTIDE BONDS | Bonds occurring in the primary protein structure (ie: in the amino acid chain) |
| ALPHA HELICES and BETA PLEATED SHEETS | Secondary protein structures (there's 2 of them!) |
