Nucleic acids (DNA and RNA) are assembled from nucleotides, which consist of three components: a nitrogenous base, a five-carbon sugar (pentose), and phosphate.. Five-Carbon Sugar. Nucleic acids (as well as nucleosides and nucleotides) are classified according to the pentose they contain. If the pentose is ribose, the nucleic acid is RNA (ribonucleic acid); if the pentose is deoxyribose, the ...
The three subunits of a nucleotide are a nitrogenous base, a sugar and a phosphate group. Nucleotides are the building blocks of DNA and RNA molecules.
The DNA molecule is made up of nucleotides. Each nucleotide contains three different components — a sugar, a phosphate group, and a nitrogen base.
Nucleotides are the basic units of nucleic acids (DNA and RNA). Nucleic acids are biomolecules essential for all forms of life. A nucleotide has 3 components: 1. Pentose sugar> 2. Nitrogenous base 3. Phosphate sugar. Pentose Sugar. It is a monosaccharide with 5 carbon atoms. It forms the backbone of polynucleotide chain. It is also of 2 types. 1.
Nucleotides are joined from the 3′ carbon of the sugar in one nucleotide to the 5′ carbon of the sugar of the adjacent nucleotide. The 3′ and the 5′ ends are chemically very distinct and have different reactive properties. During DNA replication, new nucleotides are added only to the 3′ OH end of a DNA strand.
A nucleotide has a nitrogen-containing base (either purine or pyrimidine). Purine’s bases have adenine and guanine (found in both DNA and RNA) and also have a double ring structure. The pyrimidine bases thymine (found in only DNA) have a single ring structure, and are uracil (found only in RNA), and cytosine (found in both). 2.
Nucleotides are chemical compounds that form the basic structure of nucleic acids like RNA and DNA. The chemical structure of nucleotides is almost the same regardless of whether or not the nucleotide is an RNA or DNA nucleotide. Nucleotides are made out of elements like nitrogen and carbon with a nitrogenous base, a five-carbon sugar component, and a group of phosphates.

DNA. DNA (or deoxyribonucleic acid) is the molecule that carries the genetic information in all cellular forms of life and some viruses. It belongs to a class of molecules called the nucleic acids, which are polynucleotides - that is, long chains of nucleotides. Each nucleotide consists of three components:
A polynucleotide is formed by linkage of nucleotides through phosphodiester bonds formed between the hydroxyl group at 3′-carbon of the sugar of one nucleotide and the phosphate at the 5′-carbon of the other nucleotide. A polyribonucleotide forms an RNA and a polydeoxyribonucleotide forms a DNA.
