Which of the following events is not associated with eukaryo

Which of the following events is not associated with eukaryotic mRNA synthesis?

A. Addition of the poly A tail at the 3’ end
B. None of these.
C. The binding of sigma factor to promoter
D. Assembly of initiation complex at the promoter
E. Addition of the 7-mG cap at the 5’ end
F. Removal of introns by splicing

Solution

option C is correct because sigma factor is a initiation factor (component of bacterial RNA polymerase) of bacterial transcription and it is responsible for the correct binding/ recognition of bacterial RNA plymerase to the promoter site
