| Question | Answer |
| Avery | results not accepted by most scientists, transformation prevented by DNA destroying enzymes, DNA was the genetic material |
| Hershey and Chase | added to Avery’s work, radioactive tracers, DNA stores genetic information |
| DNA | sugar is deoxyribose, double helix, made of nucleotides |
| Nucleotide | phosphate, sugar, nitrogen base |
| RNA | sugar is ribose, one strand, uracil instead of thymine, ESSAY=name and describe 3 types |
| Messenger | delivers information to ribosomes |
| Transfer | carries amino acids to mRNA |
| Ribosomal | makes ribosomes |
| Franklin | X ray diffraction, discovered helical shape |
| Wilkins and Franklin | first to suggest DNA was helix |
| Replication | occurs before cell division, one mistake every billion nucleotides, two complimentary strands unwind and unzip while being duplicated, ESSAY=describe process |
| Helicase | breaks hydrogen bonds, enzyme |
| DNA Polymerase | check for errors during replication, add nucleotides during replication |
| Translation | anticodon bonds to codon and releases amino acid into a chain, involves mRNA and tRNA, occurs at ribosomes |
| Genetic Code | same in all organisms, use table |
| Mutations | insertion, deletion, substitution |
| Insertion | a base is added |
| Deletion | a base is left out |
| Substitution | a base is put in place of another |
| Griffith | caused harmless bacteria to become deadly, |
| Watson and Crick | DNA is double stranded and twists into a double helix, established structure of DNA |
| Chargaff’s rule | A=T, C=G |
| Transcription | messenger RNA is produced, |
| Codon | nucleotide triplet specifies for specific amino acid |
| Ribosomes | 3 binding sites during translation |
