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...

Transcription - Answer synthesis of RNA from DNA Transcription results in - Answer mRNA RNA polymerase makes - Answer mRNA mRNA - Answer makes proteins RNA polymerase - Answer binds to DNA Transcription factors (TFs) - Answer A regulatory protein that binds to DNA and affects transcription of specific genes. Can wither activate or repress expression of genes Termination of transcription - Answer RNA polymerase reaches a terminator sequence (Stop codon) and ...
