Methylation of dna - Study guides, Class notes & Summaries

Core Promoter Elements ~~> TATA box = repetitive sequence of thymine and adenine Initiator (INR) = sequence of pyramidines like thymine and cytosine DPE = downstream promoter elements found along the DNA Common to have >1 promoter but not all of them CpG islands ~~> Sequences high in CG frequency. They are able to escape methylation which would lead to gene silencing. Demethylation would lead to over expression of genes. Regulatory Promoter Elements ~~> UAS and URS f...
