What are the common consensus sequences in a typical bacterial promoter?

5–TATAT–3 (–25 from start site) and 5–CGCC–3 (–35 from start site)

How are transcription and replication similar?

	Both processes require the action of a primase enzyme and DNA ligase.
	Both processes require the separation of the DNA double helix and the synthesis of a new strand of nucleic acid from a DNA template.
	Both processes use a dimeric catalytic polymerase enzyme to make two new strands of nucleic acid simultaneously.
	Both processes require RNA primers.
	Both processes require a template that can be read in a 5 to 3 direction.

What are the common consensus sequences in a typical bacterial promoter?

	5–TTGACA–3 (–35 from start site) and 5–TATAAT–3 (–10 from start site)
	5–TTGACA–3 (–35 from start site) and 5–ATG–3 (at start site)
	5–TATAAT–3 (–10 from start site) and 5–ATG–3 (at start site)
	5–TATAT–3 (–25 from start site) and 5–ATG–3 (at start site)
	5–TATAT–3 (–25 from start site) and 5–CGCC–3 (–35 from start site)

Explanation

How are transcription and replication similar?

Both processes require the separation of the DNA double helix and the synthesis of a new strand of nucleic acid from a DNA template

Yes, in both replication and transcription, they need a template created by the separation of DNA double helix to synthesize new strand of nucleic acid (DNA or RNA). RNA polymerase actually does not need a primer to initiate RNA synthesis, it is only DNA polymerase which needs a primer with a 3-hydroxyl group. So, need of RNA primase in case of transcription
