Vocab from Topic 1 (Structure & Replication of DNA) & Topic 2 (Gene Expression)
| Term | Definition |
|---|---|
| Adenine | The base found on DNA and RNA that always pairs with thymine. |
| Amino acid | The molecules joined together by peptide bonds to form polypeptides (which when folded become proteins). |
| Anticodon | The triplet of bases on a tRNA molecule that match with three bases on an mRNA strand. |
| Cytosine | The base found on DNA and RNA that always pairs with guanine. |
| Deoxyribose | The name of the sugar found in DNA. |
| DNA polymerase | The enzyme that attaches to and moves along a DNA molecule during replication. |
| Eukaryote | Any organism whose cells contain internal membranes. |
| Exons | The coding regions of mRNA that bind together to form the mature mRNA transcript. |
| Guanine | The base found on DNA and RNA that always pairs with cytosine. |
| Introns | The non-coding regions of mRNA that are spliced out of the primary transcript. |
| Ligase | The enzyme involved the joining sections of DNA together (necessary for DNA replication, genetic engineering, etc.). |
| Plasmid | A small, circular piece of DNA found in prokaryotes (e.g. bacteria). |
| Ribose | The name of the sugar found in RNA. |
| Ribosome | The structure within a cell (made from rRNA and protein) where protein synthesis takes place. |
