The structures of Deoxyribonucleic Acid and Ribonucleic Acid have several differences.
DNA - Deoxyribonucleic Acid
Consists of two strands of nucleotides bonded together by hydrogen bonds.
Nucleotides in deoxyribonucleic acid consist of a deoxyribose pentose sugar molecule, a phosphate group, and a nitrogenous base.
The nucleotides making up DNA are Thymine (T), Adenine (A), Guanine (G), and Cytosine (C)
RNA - Ribonucleic Acid
single strand of nucleotides
contains a ribose pentose sugar molecule instead of deoxyribose pentose sugar
The nucleotides making up RNA are Uracil (U), Adenine (A), Guanine (G), and Cytosine (C)
