Guanine and cytosine bonding
WebIn nucleic acid, nucleobases are held together by hydrogen bonding, which only works efficiently between adenine and thymine and between guanine and cytosine. The base complement A = T shares two hydrogen bonds, while the base pair G ≡ C has three hydrogen bonds. All other configurations between nucleobases would hinder double … WebAdenine and guanine are purines, meaning that their structures contain two fused carbon-nitrogen rings. Cytosine and thymine, in contrast, are pyrimidines and have a single …
Guanine and cytosine bonding
Did you know?
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 two tautomeric forms, the major keto form (see figures) and rare enol form. It binds to cytosine through three hydrogen bonds. In cytosine, the amino group acts as the hydrogen bond donor and the C-2 carbonyl and the N-3 amine as … WebJul 1, 2024 · The second thing you should notice in Figure 23.7. 3 is that the correct pairing enables formation of three instances of hydrogen bonding between guanine and cytosine and two between adenine and thymine. The additive contribution of this hydrogen bonding imparts great stability to the DNA double helix.

WebFeb 7, 2024 · In biology, "double helix" is a term used to describe the structure of DNA. A DNA double helix consists of two spiral chains of deoxyribonucleic acid. The shape is similar to that of a spiral staircase. … WebApr 6, 2005 · G(N2b)–C. Removing the guanine N2 hydrogen atom not used for making a hydrogen bond with cytosine gives the G(N2b)–C radical. Because this H atom is not involved in hydrogen bonding, removing it has little effect on the structure of the base pair. The hydrogen bond lengths are not expected to change in a major way.
