Are sperm-binding proteins among two closely related frog species

Meanwhile, in medicine, the apparent rarity of the inborn errors of metabolism made them irrelevant to the medical profession and efforts to show their inheritance and congenital nature were of little help to the practice of medicine in Garrod_s lifetime. Moreover, the opinion that these disorders w ...

Expanded genetic code



An expanded genetic code is an artificially modified genetic code in which one or more specific codons have been re-allocated to encode an amino acid that is not among the 22 encoded proteinogenic amino acids.The key prerequisites to expand the genetic code are: the non-standard amino acid to encode, an unused codon to adopt, a tRNA that recognises this codon, and a tRNA synthase that recognises only that tRNA and only the non-standard amino acid.Expanding the genetic code is an area of research of synthetic biology, an applied biological discipline whose goal is to engineer living systems for useful purposes. The genetic code expansion enriches the repertoire of useful tools available to science.
