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 |
