Answer:
Correct Answer: B
Solution:
[b] Sigma factor is associated with the initiation of transcription.
Sigma factor conferrs the specificity of RNA synthesis at the promoter region.
Capping involves the addition of unusual nucleotide at the 5’ end of hn RNA.
Tailing involves the addition of adenylate residues at 3’ end in a template independently.
Coding strand (also called leading strand) is a strand synthesized by an enzyme in continuous, piece in 5’ - 3’ direction.
