| 7954630050 | Operon | a group of related genes found in a prokaryote that are controlled by one regulator |  | 0 |
| 7954630051 | Operator | location in DNA where the repressor protein attaches |  | 1 |
| 7954630052 | Repressor | the regulatory protein that turns the operon off by bing to the operator |  | 2 |
| 7954630053 | On | A lac operon that is producing lactase |  | 3 |
| 7954630054 | Tryptophan operon | sequence of genes that controls the production of tryptophan | 4 | |
| 7954630055 | Regulatory Gene | codes for a repressor protein | 5 | |
| 7954630056 | Repressor Protein | Binds to the operator to inhibit transcription | 6 | |
| 7954630057 | Inducible | operon that can be turned ON default is turned OFF ex: lac operon |  | 7 |
| 7954630058 | Repressible | operon that can be turned OFF default is turned ON ex: trp operon |  | 8 |
| 7954630059 | Inducer | molecule that attaches to the repressor protein, changes its shape and removes it from the operator | 9 | |
| 7954630060 | Gene Expression | turning on and off of genes | 10 | |
| 7954630061 | Promoter | location in DNA where RNA polymerase attaches | 11 | |

| 7954630063 | lactase | enzyme that metabolizes a particular sugar | 13 | |
| 7954630064 | RNA Polymerase | enzyme that adds nucleotides during the transcription of mRNA | 14 | |
| 7954630065 | lac operon | sequence of genes that control the production of lactase | 15 | |
| 7954630068 | Structural Genes | genes found sequentially in an operon that share a common function | 16 | |
| 7954630069 | Eukaryotes | Do NOT contain operons | 17 | |
| 7954630070 | Transcription | DNA --> mRNA | 18 |
