They are often used interchangeably, however, they are quite distinct entities. 1. The most common bases present in nucleosides are adenine, cytosine, uracil, guanine, and thymine, and to a lesser extent hypoxanthine and other bases are found. Nucleotides are building blocks of nucleic acids (DNA and RNA). Examples of nucleosides include cytidine, uridine, adenosine, guanosine, thymidine and inosine. . . A long chain of different nucleotides called a polynucleotide chain . A nucleoside consists simply of a nucleobase (also termed a nitrogenous base) and a five-carbon sugar (ribose or 2-deoxyribose) whereas a nucleotide is composed of a nucleobase, a five-carbon sugar, and one or more phosphate groups. Nucleobases, also known as nitrogenous bases or often simply bases, are nitrogen-containing biological compounds that form nucleosides, which, in turn, are components of nucleotides, with all of these monomers constituting the basic building blocks of nucleic acids. For example, DNA contains two such chains spiraling round each other in the famous double helix shape. Nucleotide noun Author. This problem has been solved! SEQUENCE LISTING. protected nucleoside. Nucleoside = Carbon sugar + Nitrogenous Base Guanosine (G) = Guanine + 5-Carbon Sugar. Nucleosides are the structural subunit of nucleic acids such as DNA and RNA.
