At pH = 9.34, the OH − concentration is high (high pH = more basic = less H + = more OH − ). Therefore the OH − will be attracted to the positively charged amine group and will "steal" an H + from it.

WebGuanine has long been known to aggregate in solution, in the nucleoside, oligonucleotide, and polynucleotide forms (6).The molecular basis for this behavior is rooted in the … WebThe two sides of the DNA double helix are connected by pairs of bases (adenine, thymine, cytosine, and guanine). Because of the geometric shape of these molecules, adenine bonds with thymine and cytosine bonds with guanine. The following figure shows the thymine-adenine bond. Each charge shown is ±e and the H−N distance is 0.110 nm. (Figure 1)

Guanine (symbol G or Gua) is one of the four main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine (uracil in RNA). In DNA, guanine is paired with cytosine. The guanine nucleoside is called guanosine. With the formula C5H5N5O, guanine is a derivative of purine, … See more 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 See more The first isolation of guanine was reported in 1844 by the German chemist Julius Bodo Unger [de] (1819–1885), who obtained it as a mineral formed from the excreta of sea birds, which is known as guano and which was used as a source of fertilizer; guanine … See more The word guanine derives from the Spanish loanword guano ("bird/bat droppings"), which itself is from the Quechua word wanu, meaning "dung".
