Nucleotides definition genetics
WebA triplet sequence of DNA or RNA nucleotides corresponding to a specific amino acid or a start/stop signal in translation. WebAll four nucleotides (A, T, G and C) are made by sticking a phosphate group and a nucleobase to a sugar. The sugar in all four nucleotides is called deoxyribose. It’s a cyclical molecule—most of its atoms are arranged in a ring-structure. The ring contains one …
