MATH 221 Lecture Notes - Lecture 11: Tata Box, Polyadenylation, Adenine
Document Summary
Exons: regions of dna that code for parts of a protein. Some have tata box which binds tata-binding protein which helps anchor rna polymerase ii to promoter. The transcription initiation site, aka cap sequence : dna sequence that will code for the addition of a modified nucleotide cap at the 5 end of the. 3" poly a tail: adenine residues added by enzymes to 3" terminus of mrna transcript: confers stability on mrna can exit nucleus/ permits mrna to become protein, the 5 untranslated region (5 utr), aka leader sequence .
