| Nitrogen Bases | For example, adenine, cytosine, guanine, thymine |
| Replication | When DNA makes an exact copy of itself. |
| Gene | A portion of a DNA molecule that is the code for a single protein. |
| Codon | A triplet on mRNA. |
| Transcription | The process of making a mRNA. |
| mRNA | Carries the code from DNA to the ribosome. |
| tRNA | Brings amino acids to the ribosome. |
| Anticodon | A triplet on a tRNA, bonds to the codon. |
| Mutation | Any mistake or change in the DNA sequence. |
| Point Mutation | A change in a single base pair of DNA. |
| Frame Shift Mutation | A mutation in which a single base is added or deleted from DNA. |
| Chromosomal Mutation | A mutation at the chromosome level. |
| Watson & Crick | Discovered the structure of DNA |
| Griffith | Discovered transformation |
| Avery | Proved that DNA is responsible for transformation |
| Hersey & Chase | Discovered that DNA is the heridity material of a virus(bacteriophage) |
| Wilkins and Franklin | mad an x-ray of DNA that showed it was a helix |
| Chargaff | Showed that A=T and that G=C in any organism on earth |
| DNA | genetic material of life |
| Translation | the process of pairing tRNA with mRNA when forming a protein |
| ribosome | place where proteins are made |
| nuleotide | made with a sugar, phosphate and base |
| Adenine | Thymine pairs with this molecule in DNA |
| Cytosine | Guanine pairs with this molecule in DNA |
