Which event must occur before eukaryotic mRNA is transcribed?
A) Binding of a transcription factor to the promoter
B) Capping of the 5' end
C) Addition of a poly A tail to the 3'end
D) Splicing out of the introns
E) Transport to the cytosol

Before eukaryotic mRNA is transcribed, a transcription factor must bind to the promoter region of the DNA, which initiates the transcription process. The other events (capping, poly A tail addition, splicing, and transport to the cytosol) occur after transcription has taken place.
