Pyrimidines, which include cytosine, thymine and uracil.
and
Purines, which include adenine and guanine
The nitrogenous bases for DNA are: Adenine, Thymine, Cytosine and Guanine
for RNA they are : Adenine Uracil, Cytosine and Guanine.
They are both pyrimidines, meaning they have one carbon ring. (Also cytosine's match is adenine and thymine match is guanine.)
The two classes of nitrogenous bases are the purines and the pyramidines.
In DNA adenine pairs with thymine, and guanine pairs with cytosine. In RNA, adenine pairs with uracil instead of thymine, and guanine also pairs with cytosine.
Purines & Pyrimidines
Both DNA and RNA have nitrogenous bases. The nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). The nitrogenous bases in RNA are adenine (A), uracil (U), cytosine (C), and guanine (G). In DNA, A and T pair together, as does C and G. In RNA, C and G also pair together, but A pairs with U because U replaces T in RNA.
In RNA, the nitrogenous base of U (Uracil) is in place of T (Thymine) in DNA.
NucleotidesNucleotides are the monomers, building blocks, of nucleic acids (DNA and RNA). Each nucleotide includes three components: a phosphate, a sugar, and a nitrogenous base. The phosphate is bonded to the sugar through phosphodiester bonds and makes up the backbone of the molecule. The nitrogenous bases form the "rungs" of the ladder and are connected through hydrogen bonds. The phosphate is the same in DNA and RNA, but the sugar can be a ribose (for RNA) or a deoxyribose (for DNA). The latter is a ribose without "de-" one oxygen "-oxy-". There are four available nitrogenous bases in a DNA's nucleotides: adenine, thymine, guanine, and cytosine. RNA nucleotides feature the same bases with the exception of uracil, which replaces thymine. See related links and questions below.
THEY ARE ALL NITROGENOUS BASES IN THE DNA adenine and guanine are purines thymine and cytosine are pyrimidines
There are only 4 nitrogenous bases in DNA. These are adenine, thymine, guanine, and cytosine. Adenine will only pair with thymine, and guanine will only pair with cytosine.
The five nitrogenous bases in DNA and RNA are adenine, guanine, thymine, cytosine, and in RNA uracil.

Thiamine
Uracil is not found in DNA but in RNA.
Adenine, guanine, cytosine and thymine are the nitrogenous bases in the DNA. The thymine is replaced with the uracil in RNA.
DNA and RNA both have a sugar-phosphate backbone and nitrogenous bases. The bases found in both DNA and RNA are Adenine, Guanine and Cytosine.
DNA and RNA both have a sugar-phosphate backbone and nitrogenous bases. The bases found in both DNA and RNA are Adenine, Guanine and Cytosine.
Nitrogenous bases are used in the synthesis of nucleotides such as DNA and RNA. The bulkiest bases are the purines, guanine and adenine.
DNA is double helix and rna is single stranded and twisted
The five nitrogenous bases in DNA and RNA are adenine, guanine, thymine, cytosine, and in RNA uracil.
Purines and Pyrimidines
The nitrogenous base found in DNA but not RNA is called thymine. RNA contains the base uracil which during transcription(when genetic information is copied from DNA to RNA) pairs with the base adenine in DNA. So, DNA has four nitrogenous bases: (A) adenine, (C) cytosine, G (guanine), and T (thymine). And RNA has four nitrogenous bases: (A) adenine, (C) cytosine, G (guanine) and U (uracil)
