Proteins that initiate transcription in eukaryotes by recognizing sequences within the promoter region of a gene and attracting RNA polymerase are:

Question

Quizplus · Accepted Answer

Transcription factors are proteins that bind to specific sequences within the promoter region of a gene and attract RNA polymerase, initiating transcription. Repressors bind to specific promoter sequences and prevent RNA polymerase from binding, while inducers bind to specific regulatory sequences and enhance RNA polymerase binding. TATA boxes are specific DNA sequences found within the promoter region, but they do not attract RNA polymerase on their own. Poly A tails are added to the 3' end of mRNA molecules after transcription is complete and do not play a role in transcription initiation.
