Biology flashcards
| Term | Definition |
|---|---|
| DNA | Deoxyribonucleic acid |
| Nucleotide parts | Sugar, Phosphate, and base |
| Letters used to signify bases | (A) adenine (G) Guanine (C) Cytosine (T) Thymine |
| Complementary base pairs | C-G ,T-A |
| The process of DNA being copied | replication |
| 1953 | Watson and Clark suggested the model of the double helix |
| During replication | 2 nucleotide chains separate by unwinding and each chain serves as a template for a new nucleotide chain. |
| DNA polymerase | separate chains of DNA |
| DNA polymerase replication | replication occurs simultaneously at different points along the chain |
| Error rate | One error in every 10,000 paired nucleotides |
| RNA | is responsible for the movement of genetic information from the DNA |
| Structure of RNA | sugar, phosphate, nitrogen containing base |
| mRNA | carries genetic information from DNA |
| tRNA | binds to specific amino acids |
| rRNA | most abundant form |
| Transcription | process by which information is copied from DNA to RNA |
| The product of transcription | mRNA, tRNA, rRNA |
| Protein synthesis | the production of proteins |
| proteins | proteins are polymers |
| Amino acids | there are 20 amino acids |
