Bio DNA and RNA
| Term | Definition |
|---|---|
| TATA Box | a sequence of DNA found in the core promoter region of genes in archaea and eukaryote |
| Pribnow Box | Prokaryotic promoter, 40-50 base pairs, includes the 10 box and the 35 box |
| -10 box | 10 bases UPSTREAM from +1 site 5'-3' |
| -35 box | 35 bases UPSTREAM from +1 site 5'-3' |
| +1 site | active site for prokaryotes |
| Sigma | a protein subunit and it must bind to RNA Polymerase |
| Holoenzyme | sigma and RNA |
| RNA Polymerase | enzyme that is responsible for copying a DNA sequence into an RNA sequence READS template 3'-5' |
| 5' cap | recognition site for ribosomes |
| 3' poly A tail | important for stability and is a bunch of adeninesi |
| introns | noncoding region |
| exons | coding regions |
| RNA Splicing | removes introns and joins exons |
| transcription | RNA polymerase synthesises DNA into mRNA |
| Upstream DNA | dna in the opposite direction RNA polymerase is working |
| Downstream DNA | dna in the same direction RNA polymerase is working |
| Prokaryotes | do not have a nuclei and transcription and translation can occur simultaneously |
| Eukaryotes | have a nuclei and translation and transcription are seperated |
