Guanine (/ ˈɡwɑːniːn / ⓘ) (symbol G or Gua) is one of the four main nucleotide bases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine (uracil in RNA). In …

1 day ago · Guanine (G) is one of the four nucleotide bases in DNA, with the other three being adenine (A), cytosine (C) and thymine (T). Within a double-stranded DNA molecule, guanine bases on one …

It is a component of nucleic acids, the cell constituents that store and transmit hereditary traits. Guanine was first discovered in guano in 1846 and was isolated in 1891 from nucleic acids from which it is …

Jul 26, 2025 · Guanine is a fundamental component of genetic material, one of the four nucleobases that form the alphabet of life. It plays a role in storing and transmitting genetic information within organisms.

guanine (GWAH-neen) A chemical compound that is used to make one of the building blocks of DNA and RNA. It is a type of purine.

Guanine, a two-ring molecular structure, is one of the five defining components or nucleobases found in the nucleic acids DNA and RNA; the others being adenine, cytosine, thymine, and uracil.

Guanine is a crucial nucleobase in DNA and RNA, forming stable base pairs with cytosine and playing key roles in genetic information storage, gene regulation, and energy metabolism.

The meaning of GUANINE is a purine base C5H5N5O that codes genetic information in the polynucleotide chain of DNA or RNA.

Guanine is one of the four primary nitrogenous bases found in nucleic acids, specifically DNA and RNA. It plays a critical role in the storage and transmission of genetic information and pairs with cytosine in …

Guanine, along with adenine and cytosine, is present in both DNA and RNA, whereas thymine is usually seen only in DNA, and uracil only in RNA. Guanine has multiple tautomeric forms.
