  • Additionally, almost all the plastid protein coding genes were found to prefer ending with A/U. Mutation bias and selection pressure predominately shaped the codon bias of most genes. (springer.com)
  • Mutation and natural selection were the main forces to drive the codon bias pattern of most plastid protein coding genes. (springer.com)

  • The stretch of bases from the cap to the first methionine (AUG) codon is not translated and is called the 5′ untranslated region (UTR). (asnjournals.org)
