BIO206H5 Lecture Notes - Lecture 1: Pyrophosphate, Enzyme, Cistron
Document Summary
Includes: exon a region of a gene that is transcribed to rna and encodes part or all of a protein, introns a region of a eukaryotic gene that does not code for protein, but is transcribed to rna, & later excised, promoter a region of a gene to which rna polymerase binds to begin transcription (non coding start, utrs (5" to 3" untranslated regions) regions of a gene that are transcribed, but not translated, which contain translational control elements, enhancers transcription control elements. Dna transcription: the rules: rna is synthesized from a dna template (template strand, base sequence of rna is complementary to dna template, nucleotides added 5" 3" (always!!!, sequentially, one at a time, antiparallel to dna template, ntps are the substrate, rna syntheisis is catalyzed by rna polymerase, dna dependent, rna polymerase, eukaryotic primary transcript is almost always processed, hnrna mrna protein.
