Guanine.
Carbon, hydrogen, oxygen, nitrogen, phosphorus
DNA does in fact contain cytosine. This is one of the 4 nucleic acids that are found inside of DNA.
The common element in both nucleic acids and protein structure is nitrogen. Nitrogen is a key component of both nucleic acids (DNA and RNA) where it forms part of the nucleotide bases, and in proteins where it is found in amino acids as part of the protein backbone.
In the case of adenine bonding to thymine, the NH group of the thymine bonds with the N of the adenine, and the double-bonded oxygen on the thymine bonds with the NH2 group on the adenine. (thymine)N - H - N(adenine) and (thymine)=O - H - NH(adenine) In the case of guanine bonding to cytosine, the double-bonded O group of the cytosine bonds with the NH2 of the guanine, the N on the cytosine bonds with the NH group on the guanine, finally, the NH2 on the cytosine bonds with the double-bonded O on the guanine. (cytosine)=O - H - NH(guanine) and (cytosine)N - H - N(guanine) finally (cytosine)NH - H - O=(guanine) In summary, there are two H bonds between an adenine and a thymine. There are three H bonds between a cytosine and guanine.
Adenine and Thymine Guanine and Cytosine held together by hydrogen bonds: 2 for A-T and 3 for G-C
nucleic acid is not a single element nucleic acid is a complex molecule contain elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur etc
Nitrogen is the element primarily found in proteins and nucleic acids. It plays a crucial role in the structure and function of these biomolecules, including forming peptide bonds in proteins and base pairs in nucleic acids.
Carbon, hydrogen, oxygen, nitrogen, phosphorus
Guanine is one of the four main nucleobases found in DNA and RNA. It pairs with cytosine through three hydrogen bonds in DNA. Guanine is essential for the formation of the genetic code and plays a key role in the structure and function of nucleic acids.
Carbon, hydrogen and oxygen and nitrogen.
Proteins are made of amino acids. Nucleic acids are made of a sugar (ribose in RNA and deoxyribose in DNA), a phosphate group and nitrogen bases [thymine (or uracil in RNA), cytosine, guanine, and adenine].
DNA does in fact contain cytosine. This is one of the 4 nucleic acids that are found inside of DNA.
Nitrogen, Oxygen, Phosphorus, Sulfur, Carbon and Hydrogen.
There are several elements in all proteins and all nucleic acids:Hydrogen,Carbon,Oxygen, andNitrogen.All nucleic acids also contain a lot of phosphorus and commonly proteins contain a tiny bit too, but that is not really relevant to the intention of the question.
The common element in both nucleic acids and protein structure is nitrogen. Nitrogen is a key component of both nucleic acids (DNA and RNA) where it forms part of the nucleotide bases, and in proteins where it is found in amino acids as part of the protein backbone.

There are three H bonds between a cytosine and guanine.
The subunit structure of nucleic acid consists of nucleotides, which are composed of a sugar molecule (ribose or deoxyribose), a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil). These nucleotide monomers join together via phosphodiester bonds to form strands of nucleic acid, such as DNA or RNA.
