| Question | Answer |
|---|---|
| 4 nitrogen bases of DNA | Thymine, guanine, adenine, and cytosine |
| 4 nitrogen bases of RNA | Adenine, Thymine, Guanine, and Uracil |
| Purine | Double ring bases |
| Pyramidine | Single ring bases |
| Double helix | The coiled structure of double-stranded DNA in which strands linked by hydrogen bonds form a spiral configuration, with the two strands oriented in opposite directions. |
| Complementary base pair | the nucleotide bases in one strand of DNA or RNA that are paired with that in another strand: adenine pairs with thymine or uracil and guanine pairs with cytosine |
| replication | The process of duplicating or producing an exact copy of a polynucleotide strand such as DNA. |
| transcription | the process of forming a nucleic acid by using another molecule as a template |
| translation | the portion of protein synthesis that takes place at ribosomes and that uses the codons in mRNA molecules molecules to specify the sequence of amino acids in polypeptide chains |
| base sequence | The order of nucleotide bases in a dna molecule |
| helicases | an enzyme that separates DNA strands |
| replication fork | a Y-shaped point that results from when the two strands of a DNA double helix separate so that the DNA molecule can be replicated |
| DNA polymerases | an enzyme that catalyzes the formation of the DNA molecule |
| RNA polymerases | an enzyme that starts the formation of RNA by using a strand of a DNA molecule as a template |
| mRNA | a single-stranded RNA molecule that encodes the information to make a protein |
| tRNA | an RNA molecule that transferes amino acids to the growing end of a polypeptide chain during translation |
| rRNA | an organelle that contains most of the RNA in a cell and that is responsible for ribosome function |
| promotion(start) | a nucleotide sequence on a DNA molecule to which an RNA polymerase molecule binds which initiates the transcription of a specific gene |
| termination (stop) | a nucleotide triplet within messenger RNA that signals a termination of translation.[ |
| codon | in DNA a three nucleotide sequence that encodes an amino acid or signifies a start signal or a stop signal |
| anticodon | a region of tRNA that consists of three bases complementary to the codon of RNA |
| genome | the complete genetic material contained in an individual |
| 22/22 | Know which bases are purines and which pyrimidines. Do you understand transcription from your definition? |
