Both are nucleic acids and made out of nucleotides; however, RNA is single-stranded while DNA is double-stranded. RNA nucleotides, like those from DNA, have three parts: a 5-carbon sugar, a phosphate group, and a base. RNA contains the 5-carbon sugar ribose, whereas, in DNA, the sugar is deoxyribose.

Nucleic acid structure refers to the structure of nucleic acids such as DNA and RNA. Chemically speaking, DNA and RNA are very similar. Nucleic acid structure is often divided into four different levels: primary, secondary, tertiary, and quaternary.
DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are composed of two different classes of nitrogen-containing bases: the purines and pyrimidines. The most commonly occurring purines in DNA are adenine and guanine: Figure 1.2.1: Purines. The most commonly occurring pyrimidines in DNA are cytosine and thymine: Figure 1.2.2: Pyramidines
Illustration of the structure and nucleotide bases of the genetic molecules ribonucleic acid (RNA, left) and deoxyribonucleic acid (DNA, right). The nucleotide bases are cytosine (C), guanine (G), adenine (A), thymine (T) and uracil (U).
23 Αυγ 2020 · Three differences between DNA and RNA are that DNA uses the base thymine while RNA uses uracil, DNA uses the sugar deoxyribose while RNA uses ribose, and usually DNA is double-stranded and RNA is single-stranded. (image: Sponk, Creative Commons 3.0)
31 Οκτ 2023 · The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the chloroplasts and mitochondria.
A nucleotide has three components: a sugar molecule, a phosphate group, and a nitrogenous base. The sugar in DNA’s nucleotides is called deoxyribose—DNA is an abbreviation for deoxyribonucleic acid. RNA molecules use a different sugar, called ribose.
