The Evolution of tRNA-Leu Genes in Animal Mitochondrial Genomes [PDF]

open access: yesarXiv, 2003
Animal mitochondrial genomes usually have two transfer RNAs for Leucine: one, with anticodon UAG, translates the four-codon family CUN, whilst the other, with anticodon UAA, translates the two-codon family UUR. These two genes must differ at the third anticodon position, but in some species the genes differ at many additional sites, indicating that ...

Quantum magnetic imaging of iron biomineralisation in teeth of the chiton Acanthopleura hirtosa [PDF]

open access: yesarXiv, 2019
Iron biomineralisation is critical for life. Nature capitalises on the physical attributes of iron biominerals for a variety of functional, structural and sensory applications. Although magnetism is an integral property of iron biominerals, the role it plays in their nano-assembly remains a fundamental, unanswered question.
