The thymine (T) base on one strand can form two H-bonds with an adenine (A) base on the other strand (this is called an AT base pair).
WebCytosine is a constituent present in both DNA and RNA. It is complementary to guanine and held by three hydrogen bonds. Oxygen atom in the keto group, N-3 and one of the Hydrogen atoms in the amino group are involved in hydrogen bond formation with guanine. Cytosine is not chemically stable.

Qualitatively, guanine (G) and cytosine (C) undergo a specific hydrogen bonding with each other, whereas adenine (A) bonds specifically with thymine (T) in DNA and with uracil (U) in RNA. Quantitatively, each GC base pair is held together by three hydrogen bonds, while AT and AU base pairs are held together by two hydrogen bonds. To emphasize this difference, the base pairings are often represented as "G≡C" versus "A=T" or "A=U". tatuaggi addomeWebAdenine (A) a purine base and Uracil (U) a pyrimidine base, both make complementary base pairs in a RNA structure by forming hydrogenous double bonds between them, this … tatuaggi adesivi swarovskiWeb23 aug. 2024 · Hydrogen bonds between the base pairs hold a nucleic acid duplex together, with two hydrogen bonds per A-T pair (or per A-U pair in RNA) and three hydrogen bonds per G-C pair.
