When examining the basic components of DNA, the mole percentage of guanine is comparable to cytosine and the mole percentage of adenine is according to thymine [3]. Nucleobases, also known as nitrogenous bases or often simply bases, are nitrogen-containing biological compounds that form nucleosides, which, in turn, are components of nucleotides, with all of these monomers constituting the basic building blocks of nucleic acids. The chemical structure of cytosine (C) is {eq}C_{4}H_{5}N_{3}O {/eq}. The main difference between adenine and guanine is that adenine contains an amine group on C-6, and an additional double bond between N-1 and C-6 in its pyrimidine ring whereas guanine contains an amine group on C-2 and a carbonyl group on C-6 in its pyrimidine . The purines are adenine and guanine. Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. DNA Replication, Structure & Function | What is DNA? Adenosine is the larger nucleotide molecule made up of adenine, ribose or deoxyribose, and one or more phosphate groups. Substituted Watson-Crick guanine-cytosine (GC) base pairs were recently shown to yield robust three-state nanoswitches. Thus, cytosine, along with adenine and guanine, is present in both DNA and RNA, whereas thymine is usually seen only in DNA and uracil only in .
