Adenine, Thymine, Cytosine and Guanine. Uracil substitutes for Thymine in RNA.
nucleotides chargaff and the structure question
A DNA nucleotide includes a phosphate, a deoxyribose sugar and a nitrogenous base. Only the nitrogenous base changes in the four different nucleotides. The four different bases are adenine (A), thymine (T), cytosine (C) and guanine (G).
DNA is a polymer of nucleotides. A DNA molecule consists of three parts—a nitrogen base, a five-carbon sugar called deoxyribose, and a phosphate group.There are four DNA nucleotides, each with one of the four nitrogen bases (adenine, thymine, cytosine, and guanine). The first letter of each of these four bases is often used to symbolize the respective nucleotide (A for adenine nucleotide, for example)
There are four nitrogen bases found in DNA: adenine, guanine, cytosine, and thymine.
Thymine is one of the four possible bases which, when attached to a phosphate group and a molecule of deoxyribose, forms a nucleotide; nucleotides are the monomer units of DNA.
The four RNA nucleotides are named for their nitrogen bases. They are adenine, uracil, cytosine, and guanine.
nucleotides chargaff and the structure question
The purines adenine and guanine are two of the four nitrogen bases in DNA. There are many other purines that are found in nature, but not in DNA.
DNA has four types of nucleotides, each of which contains one of four nitrogen bases: adenine, thymine, guanine, and cytosine.
These are four types of amines found in DNA. They are four nucleotides, which carry nitrogen, which in turn are the building blocks of DNA and RNA. The are often called "nucleotide bases" or just "bases". They form base pairs: A with T, G with C.
A DNA nucleotide includes a phosphate, a deoxyribose sugar and a nitrogenous base. Only the nitrogenous base changes in the four different nucleotides. The four different bases are adenine (A), thymine (T), cytosine (C) and guanine (G).
Nucleotides contain a 5-carbon sugar, phosphate, and one of four nitrogen bases; adenine, thymine, guanine, cytosine, and uracil in place of thymine in RNA.
The four nitrogen bases of DNA are naturally occuring amines and sometimes they are synthesized from amino acids in vivo.
DNA nucleotides are composed of the sugar deoxyribose, a phosphate group, and one of four nitrogen bases: adenine(A), thymine(T), guanine(G), cytosine(C).

DNA is composed of nucleotides which contain the 5-carbon sugar deoxyribose, a phosphate molecule, and one of four nitrogen bases: adenine, thymine, guanine, and cytosine. These nucleotides form two strands of DNA which twist around one another to form a double helix. The sequence of the nitrogen bases determines a cell's structure and function, and determines heredity.
