Figure 4 in The first genomic resource for the 'near threatened' Neotropical otter Lontra longicaudis (Carnivora: Mustelidae): mitochondrial genome characterisation and insights into phylomitogenomic relationships in the family Mustelidae

Figure 4. tRNAs in the mitochondrial genome of Lontra longicaudis usually display 'cloverleaf̍ secondary structures; however, in Serine 1 (tRNA-Ser(AGY) or trnS1), the DHU loop (3–4bp) was absent. The truncation of this tRNA is a conserved trait in metazoans.
