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 |
