Vocabulary Practice
| Term | Definition |
|---|---|
| DNA Replication | The process that involves DNA being copied |
| Codon | A sequence of 3 nucleotide bases located on the mRNA |
| Anticodon | A sequence of 3 nucleotide bases located on the tRNA that is complimentary to the mRNA |
| Watson and Crick | scientists who were given credit for the discovery and creation of a model of DNA |
| Central Dogma | States that the order of protein synthesis occurs in the following DNA --> RNA --> Protein |
| DNA Polymerase | The enzyme that is required for DNA replication and builds the new daughter strands that are complimentary to the parent strands |
| RNA Poylmerase | The enzyme required for transcription that builds and assembles the mRNA strand from the DNA template. |
| Chargaff's Rule | discovered that in DNA there is always an equal amount of Adenine to Thymine and the amount of Cytosine to Guanine and gave rise to the Base Pair Rule A-T and C-G. |
| mRNA | carries the code from the nucleus to the ribosome |
| rRNA | type of RNA that is found in ribosomes and helps assist in translation |
| tRNA | a type of RNA that transfers an amino acid that correlates with the codon during translation |
| Start codon | a sequence of bases that signals the start of protein synthesis which is AUG and codes for the amino acid Methionine |
| DNA | Deoxyribonucleic Acid Made of nucleotides that contains deoxyribose sugar contains A,C,T,G Double stranded Stays in the nucleus |
| RNA | Ribonucleic Acid Made of nucleotides that contains ribose sugar Single stranded Contains the bases A, C, G and U is small in size and can travel out of the nucleus |
| Transcription | The process of converting a sequence of DNA to mRNA |
| Translation | The process of converting a strand of mRNA to a polypeptide protein |
| Rosalind Franklin | The scientists that provided the first actual image of DNA using X-Ray crystallography which helped to determine the shape of DNA as a double helix |
| Helicase | The enzyme that is responsible for unzipping DNA double strands during DNA replication |
| Sugar-Phosphate Backbone | is made of deoxyribose and phosphate groups covalently bonded together to form the "sides" of the DNA "ladder" |
| Hydrogen bonds | The type of bonds that form between the nitrogen bases and forms the "steps" of the DNA "ladder" |
| Protein Synthesis | The process of making proteins by joining amino acids together with a peptide bond. |
