No. Deoxyribose is the sugar in a DNA nucleotide. A DNA nucleotide would also include a phosphate group and a nitrogen base.
One can determine whether a nucleotide is DNA or RNA by looking at the sugar molecule it contains. DNA nucleotides have deoxyribose sugar, while RNA nucleotides have ribose sugar. This difference in sugar molecules helps distinguish between the two types of nucleotides.
A nucleotide polymer is a long chain made up of nucleotide units bonded together. Each nucleotide consists of a nitrogenous base, a sugar molecule, and a phosphate group. Nucleotide polymers form the backbone of DNA and RNA molecules.
The nitrogenous base can differ from one nucleotide to another. It can be adenine, guanine, cytosine, or thymine (in DNA) or uracil (in RNA). The sugar and phosphate components remain the same in all nucleotides.
The key difference between a DNA nucleotide and an RNA nucleotide is their five-carbon sugar molecules. One component of RNA is the five-carbon sugar ribose, C5H10O5. Alternatively, in DNA, the five-carbon sugar deoxyribose (C5H10O4) has one fewer oxygen atom. Another difference is in the nitrogenous bases of some DNA and RNA nucleotides. The nitrogenous base uracil (U) is unique to RNA nucleotides. Similarly, the nitrogenous base thymine (T) is unique to DNA nucleotides.
Adenine occurs in both RNA and DNA molecules. It is uracil that replaces thymine in the RNA molecule.
A combination of a sugar, a phosphate group, and a nitrogen base is called a nucleotide. Nucleotides are the building blocks of nucleic acids like DNA and RNA. The nitrogen base can be adenine, guanine, cytosine, thymine (in DNA), or uracil (in RNA).
