Viral 5′ UTRs Are Conserved, Related to Figure 2
Multiple sequence alignments of unique H1N1 IAV 5′UTRs per genome segment (n = 10904). The overall distribution of each unique nucleotide sequence is indicated on the left, and the consensus sequence of each UTR is indicated below each alignment. The top panels show the positional weight matrix of each nucleotide across the UTRs.
