| Beadle and Tatum | made connection between genes and enzymes |
| gene-one enzyme hypothesis | each gene somehow controls the production of one type of enzyme |
| gene-one polypeptide | a gene is a region of DNA that controls the instructions for the manufacture of one particular polypertide chaine |
| Bases of DNA | G, C, T, A |
| protein synthesis | the manufacturer of proteins ( actual assembly takes place on ribosomes, not nuclei) |
| Differences in structure of DNA and RNA | Dna- double strand RNA - single strand |
| Purines of DNA and RNA (seperately) | DNA - A and G RNA -A and G |
| Pyramindines of DNA and RNA seperately | DNA - C and T, RNA - C and U |
| Differences of sugars in DNA and RNA | DNA - Deoxyribose RNA - ribose |
| messenger RNA | carries coded instructions for protein synthesis from DNA in the nucleus to the ribsome |
| transfer RNA | brings the amino acids to the ribosome in the correct order so that they can be built into the new protein |
| ribosomal RNA | alone with several proteins, makes up the structure of the ribosome |
| transcription | the process of transferring information from a strand of DNA to a strand of RNA |
| codon | a three base code in DNA or mRNA |
