Figure 4.

Partial sequence of KRTHAP1 exon 1 of the Indigirka woolly mammoth (Mammuthus primigenius), aligned to respective sequences from savanna elephant (Loxodonta africana) and human (Homo sapiens). For each species, both DNA (above) and amino acid sequences (below, in boldface) are shown. Premature stop codons predicted for the elephantids are indicated (after which no amino acids are shown for them). Mammoth consensus sequence was generated from clones of two independent PCR reactions (not shown); genomic sequences were used for the other two species.
