WebExpert Answer. 3) a. Guanine The purine bases present in nucleic acids are Adenine and Guanine , while the pyrimidine bases are cytosine, uracil and thymine. In DNA the bases present are adenine, guanine, cytosine and thymine while in RNA inste …. View the full answer. Transcribed image text: Cytosine can be found as part of DNA, as part of RNA, or as a part of a nucleotide. As cytidine triphosphate (CTP), it can act as a co-factor to enzymes, and can transfer a phosphate to convert adenosine diphosphate (ADP) to adenosine triphosphate (ATP). In DNA and RNA, cytosine is paired with guanine. However, it is … See more Cytosine (symbol C or Cyt) is one of the four nucleobases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents … See more Cytosine was discovered and named by Albrecht Kossel and Albert Neumann in 1894 when it was hydrolyzed from calf thymus tissues. A structure was proposed in 1903, and was synthesized (and thus confirmed) in the laboratory in the same year. See more • Cytosine MS Spectrum • EINECS number 200-749-5 • Shapiro R (1999). "Prebiotic cytosine synthesis: a critical analysis and implications for the origin of life". Proc. Natl. Acad. Sci. … See more When found third in a codon of RNA, cytosine is synonymous with uracil, as they are interchangeable as the third base. When found as the second base in a codon, the third is … See more Until October 2024, Cytosine had not been found in meteorites, which suggested the first strands of RNA and DNA had to look elsewhere to obtain this building block.
