Fig. 2From: Polymorphism of mitochondrial tRNA genes associated with the number of pigs born aliveThe predicted tertiary structures of mitochondrial tRNA-Val (a), tRNA-Ala (b), tRNA-Glu (c), and tRNA-Thr (d), respectively. The left ones referred to the reference structure of NC_000845.1, while the right were the structure with mutation sites. The dotted bases were polymorphic and affected the structure in the studyBack to article page
