WebThere are five nitrogen bases that are found in nucleic acids. Adenine, guanine, thiamin and cytosine are found in DNA, whereas, Adenine, guanine, uracil and cytosine are found in RNA. These nitrogen bases pair up very specifically and are held together by weak hydrogen bonds. Adenine always pairs up with thymine by two hydrogen bonds while ... WebJul 5, 2024 · 12 Which is the nitrogenous base present only in RNA but not in DNA? ... There are four nitrogenous bases found in RNA: adenine, guanine, cytosine, or uracil. Adenine and guanine are known as purine bases while cytosine and uracil are known as pyrimidine bases (Figure 19.6. 3).
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).
