Thymine, cytosine
Adenine and Guanine are the two classes of nitrogenous bases that belong to purines.
Adenine and Guanine belong to the class of nitrogenous bases called purines. They are characterized by a double-ring structure that includes both a six-membered ring and a five-membered ring. These purine bases play a crucial role in the structure of DNA and RNA molecules.
Guanine and Adenosine
The pyrimidines are a class of nitrogenous bases that includes cytosine, thymine, and uracil. These bases are found in nucleic acids like DNA and RNA, where they pair with complementary purines to form the building blocks of genetic information.
adenine guanine thymine cytosine
A pyrimidine group consists of only three nitrogenous bases: Uracil, Thymine, and Cytosine. All three are nitrogenous bases, so all three are the answer.
In nitrogenous bases, the nitrogen-containing molecules that are part of DNA and RNA structures, the bases are called adenine (A), thymine (T), cytosine (C), guanine (G) in DNA; and adenine (A), uracil (U), cytosine (C), guanine (G) in RNA.
Four, out of whish 2 purines and two pyremidines
The five nitrogenous bases in DNA and RNA are adenine, guanine, thymine, cytosine, and in RNA uracil.
The name of the double ring nitrogenous bases found in nucleotides is a double-helix. Nucleotides are the building blocks of nucleic acids such as RNA and DNA.
The two nitrogenous bases that are purines are adenine and guanine.
