dna are made of two sequences of nucleotides linked together
nucleotide_structure_sequence is list. nucleotide_structure_sequence is not list. codon_sequence is genetic_structure_of_ribonucleotides. genetic_structure_of_ribonucleotides is genetic_structure_of_nucleotides. nucleic_acid_sequence is nucleotide_structure_sequence. dna_molecule is dna. dna_strand is polynucleotide_strand. dna_molecule_nucleotide is nucleotide. codon_sequence is not genetic_structure_of_ribonucleotides. dna is molecule.
