Here are aligned sequences from 6 different promoters promot

Here are aligned sequences from 6 different promoters:

promoter 1:   GATGTCAAACATC

promoter 2:   AAGGTAAAGCACT

promoter 3:   GAGCTCAGGCATT

promoter 4:   GGTGTCAAGTATA

promoter 5:   CAGTTCATGCGAT

promoter 6:   GAGGCCAAACATC

Part A

What is the promoter consensus sequence, based on these 6 promoters?

Solution

promoter 1:   GATGTCAAACATC

promoter 2:   AAGGTAAAGCACT

promoter 3:   GAGCTCAGGCATT

promoter 4:   GGTGTCAAGTATA

promoter 5:   CAGTTCATGCGAT

promoter 6:   GAGGCCAAACATC

Based on the given sequences the conserved promoter consensus sequence will be AAAGCACT.
