Modified nucleobases – PubMed
Various molecules which are similar to the natural nucleobases exist in nature or have been synthetically developed. In this chapter we review work on the photophysical properties of several modified nucleobases, focusing particularly on how these properties differ from those of the natural nucleobases. We discuss studies that give physical insight into how the molecular structure can be related to photophysical properties with many of these studies being theoretical. One useful …

According to that review the fluorescent analogues of nucleobases can be categorized as following: (1) chromophoric base analogues, (2) pteridines, (3) expanded nucleobases, (4) extended nucleobases, and (5) isomorphic nucleobases. These categories help navigate through the increased number of fluorescent probes that have been developed.

High resolution mapping of modified DNA nucleobases using … – PubMed
The incorporation and creation of modified nucleobases in DNA have profound effects on genome function. We describe methods for mapping positions and local content of modified DNA nucleobases in genomic DNA. We combined in vitro nucleobase excision with massively parallel DNA sequencing (Excision-se …

Nucleobase – Wikipedia
Five nucleobases— adenine (A), cytosine (C), guanine (G), thymine (T), and uracil (U)—are called primary or canonical. They function as the fundamental units of the genetic code, with the bases A, G, C, and T being found in DNA while A, G, C, and U are found in RNA. Thymine and uracil are distinguished by merely the presence or absence of a …

Nucleobase Definition and Examples – Biology Online Dictionary
Artificial nucleobases . Certain nucleobases are artificially produced. Examples of nucleobase analogues are isoguanine and isocytosine. Isoguanine is an isomer of guanine that can be produced by oxidative damage to DNA. One of its applications is for use as a nucleobase in hachimoji nucleic acids. Isocytosine is an isomer of cytosine that can be synthesized from guanidine and malic acid. One of its uses is for use as a nucleobase in

3 Modified Nucleobases Found in Bacteriophages Jump To Collectively, bacteriophages contain the greatest diversity of modified bases so far observed in nature. These modified nucleobases include not only the products of host or bacteriophage encoded methyltransferases, but also more unusual modifications not seen in the DNAs of other organisms.

Other 96 H-bonded bases involving a noncanonical nucleobase deriving from modification of uracil were recorded, making uracil the overall most frequently modified nucleobase in RNA, see Figure 2B. The remaining three nucleobases adenine, guanine and cytosine were found to be modified in 66, 82 and 60 pairs, respectively. Figure 2.
