We have been using the term "nucleotide". a nucleotide consists of a phosphate group, a sugar, and a nitrogenous base. dna and rna are long strands of nucleotides bonded together at the sugar-phosphate backbone and across at the nitrogenous bases. in the gizmo questions, you learned that a nucleotide has a different name before the phosphate group is attached. what is the name for a nucleotide before it is attached to a phosphate group? :
nucleoside

nucleotidal

nuclear tide

Nucleoside is the name for a nucleotide before it is attached to a phosphate group

Explanation:

Cells and extracellular solutions in organisms include small concentrations of nucleosides, compounds of a base and a sugar outwardly a phosphate. Nucleotides are nucleosides that have one, two, or three phosphate groups esterified at the 5′ hydroxyl.

A nucleoside consists clearly of a nucleobase which is referred as nitrogenous base in general and a five-carbon sugar ribose whereas a nucleotide is comprised of a nucleobase, a five-carbon sugar, and more than one phosphate groups. Nucleosides are normally achieved by chemical or enzymatic decomposition of nucleic acids.
