This kind of sounds like the same thing. Both are correct depending on how you look at it. If your're talking about how it occurs biochemically then the base is attached to the sugar and phosphate.
Nucleotides are attached to each other through a sugar-phosphate backbone. The phosphate group of one nucleotide is attached to the sugar molecule of another nucleotide, forming a chain. Additionally, nucleotides are also attached to nitrogenous bases, such as adenine, cytosine, guanine, or thymine (in case of DNA) or uracil (in case of RNA).
Deoxyribose (the chain of alternating sugar/phosphate links)
ATP also called adenosine triphosphate.It is based around the same nitrogenous base as the DNA and RNA adenine nucleotide is, except it is not attached to a sugar and has three phosphate groups instead of the one phosphate group that the adenine nucleotide has.
nucleotide = in a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base. The subunit in a nucleic acid chain that consists of a sugar a phosphate and a nitrogenous base is a nucleotide.
A nucleotide is composed of: 1.) A nitrogenous base (either a purine such as Adenine or Guanine, or a pyrimidine such as a Thymine or Cytosine; Uracil is the nitrogenous base that replaces Thymine in RNA) 2.) A ribose sugar (5 Carbon ring) 3.) A phosphate group The nitrogenous base is attached to Carbon 1 on the ribose sugar while the phosphate group is attached to Carbon 5 of the same sugar. (That same phosphate group is attached to Carbon 3 of a neighboring sugar when forming a strand.)
They are attached to a deoxyribose sugar.
They are attached to a deoxyribose sugar.
They are attached to a deoxyribose sugar.
because they are okay!
They are attached to a deoxyribose sugar.
The nucleotide 'rung' covalently attaches [chemically bonds] to the Ribose sugar moiety of the Dna's phosphate-sugar backbone.

Nucleotide is the monomer. Nucleotide is the monomer of Nucleic Acids.
