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)
DNA is made up of nucleotide bases bonded to a sugar-phosphate backbone. This backbone consists of alternating sugar and phosphate molecules, with the nucleotide bases (adenine, thymine, cytosine, and guanine) attached to the sugar molecules.
The phosphate group can be removed from a nucleotide without breaking the polynucleotide chain within a DNA molecule. The phosphate group is attached to the 5' carbon of the sugar molecule in a nucleotide through a phosphodiester bond, which does not affect the backbone of the DNA chain when cleaved.
The sides or railings of DNA consist of sugar-phosphate backbones, to which nucleotide bases are attached. The nucleotide bases are the adenine (A), thymine (T), cytosine (C), and guanine (G) that form the genetic code within the DNA molecule.
The phosphate is attached to the 5' carbon of the sugar in a nucleotide.
They are attached to a deoxyribose sugar.
They are attached to a deoxyribose sugar.
They are attached to a deoxyribose sugar.
The nucleotide to which the nitrogen base is attached in DNA is the sugar molecule, specifically the deoxyribose sugar. The nitrogen base is attached to the 1' carbon of the deoxyribose sugar through a glycosidic bond.
The phosphate group of a nucleotide contains phosphorus. It is attached to the sugar molecule in a nucleotide structure, along with a nitrogenous base.
because they are okay!
The nucleotide rung of a DNA molecule is attached to the DNA backbone that consists of alternating deoxyribose sugars and phosphate groups. The nucleotide rung itself is composed of a nitrogenous base (e.g., adenine, thymine, guanine, cytosine) attached to a sugar molecule.
They are attached to a deoxyribose sugar.
The region of a nucleotide to which the nitrogen base is attached in DNA is the sugar molecule, specifically the deoxyribose sugar. The nitrogen base is connected to the 1' carbon of the deoxyribose sugar in the nucleotide structure.
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).
Yes. Thymidylate is a nucleotide. dTMP is a deoxyribonucleotide comprised of thymine, the pentose sugar deoxyribose and phosphate. It is the only nucleotide unique to DNA.
