Fig. 3From: Genome-scale portrait and evolutionary significance of human-specific core promoter tri- and tetranucleotide short tandem repeatsMultiple sequence alignment of the TSS-flanking 5′UTRs. Examples of ClustAl Omega sequence alignment are represented in the tri- (a) and tetranucleotide (b) categories.
