  • Nucleotide - Wikipedia
    Nucleotides are organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth
  • Nucleotide - National Human Genome Research Institute
    A nucleotide is the basic building block of nucleic acids RNA and DNA are polymers made of long chains of nucleotides
  • Nucleotide | Description, Types, Function, Facts | Britannica
    DNA is made of nucleotides A nucleotide has two components: a backbone, made from the sugar deoxyribose and phosphate groups, and nitrogenous bases, known as cytosine, thymine, adenine, and guanine Genetic code is formed through different arrangements of the bases
  • Nucleotide Definition, Structure, and Function
    What Is a Nucleotide? A nucleotide is an organic molecule that serves as the building block for nucleic acids like DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) These molecules consist of three primary components: a nitrogenous base, a sugar molecule, and one or more phosphate groups
