| Gene | Sequence of Nucleotide bases found in DNA, code for Polypeptide. |
| DNA Triplet | 3 bases of DNA that code for 1 Amino Acid |
| Degenerate | Most Amino Acids have more than one code |
| Stop codes | Indicate end of polypeptide chain |
| Transcription | Production of mRNA from DNA |
| mRNA | Messenger RNA |
| Telomers | Protect end of chromosome from deterioration during replication |
| Translation | Formation of polypeptide using mRNA |
| tRNA | Transfer RNA |
| Junk DNA | Non-coding. Function not discovered or Regulatory function. |
| SiRNA (Small interfering RNA) | Artificially made to stop translation and gene expression |
| Substitution Mutations | One base pair replaces another. Can change 1 Amino Acid. Or Silent mutation. |
| Insertion/Deletion | 1< Nucleotide pairs inserted or deleted. Causes frame shift |
| Cause of DNA | Mutagen, UV, X-ray, Gamma & Carcinogen |
| Operon | Made up of structural gene, code for enzymes, control elements and regulatory gene. |
| Lac Operon | Stops transcription of enzymes in absence of lactose. Induce production in presence of lactose. |
| Structural genes | Z coes for β Galactose. Y for Lactose permease |
| Operator region | Repressor molecule binds to. Turns on/off transcription of Y/Z |
| Promoter region | RNA polymerase binds to begin transcription of Y/Z |
| Homeobox | Control development of zygote onto complete organism. |
| Apoptosis | Programmed cell death. Removed unwanted structures |
