Question

Quizplus · Accepted Answer

Transcription of eukaryotic genes involves the binding of RNA polymerase to the promoter region. This is necessary for the initiation of transcription and the synthesis of mRNA. Transcription factors may also be involved in the regulation of gene expression, but their binding is not sufficient for transcription to occur. Capping and polyadenylation of the mRNA occur after transcription and are not involved in the initiation of transcription. The TATA box is a promoter element that is recognized by transcription factors and is not typically blocked by a repressor.
