an organic molecule consisting of a hereocyclic base attached to the 1-carbon of a deoxyribose ring, with a phosphate group esterified at the 5 position of the deoxyribose. Deoxyribonuceotides are the monomer units which make up deoxyribonucleic acid, the molecule carrying the hereditary information in most organisms. The most common forms of deoxyribonuceotide are thymidine-5´-phosphate (abbreviated TMP), deoxyadenosine-5´-phosphate (abbreviated dAMP), deoxyguanosine-5´-phosphate (abbreviated dGMP), and deoxycytidine-5´-phosphate (abbreviated dCMP).
A nucleotide in DNA.
a nucleotide consisting of the five-carbon sugar deoxyribose, a phosphate group, and one of four nitrogen-containing bases (adenine, guanine, cytosine, or thymine)
A subunit of DNA or RNA consisting of a nitrogenous base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA and ribose in RNA). Thousands of nucleotides are linked to form a DNA or RNA molecule. See DNA, base pair, RNA.
A nucleotide that contains deoxyribose and is a component of DNA.
A deoxyribonucleotide is the monomer, or single unit, of DNA, or deoxyribonucleic acid. Each deoxyribonucleotide is comprised of three parts: A nitrogenous base, a deoxyribose sugar, and one or more phosphate groups. The nitrogenous base is always bonded to the 1' carbon of the deoxyribose, which is distinguished from ribose by the presence of a proton on the 2' carbon rather than an -OH group.
