The correct answer to this question is guanine and adenine. The hydrolysis of nucleotides produces two types of nitrogenous bases; purine and pyrimidine. While adenine and guanine are nitrogenous bases that are of the purine type, uracil or 2,4-dioxoypyrimidine, thymine or 5-methyl-2,4-dioxipyrimidine, and cytosine or 2-oxo-4-aminopyrimidine are nitrogenous bases that are of the pyrimidine type.

The easiest way to differentiate between purines and pyrimidines is that both consist of different numbers of rings. For instance, pyrimidines only have a single ring, while purines have two rings. Unlike in purines where adenine and guanine exist in both RNA and DNA, only one of the three main types of pyrimidines exists in both RNA and DNA.

That means cytosine is the only type of pyrimidine that is present in both DNA and RNA. The structures of purines consist of four nitrogen rings, while the structure of pyrimidines only consists of two nitrogen rings.

The nitrogenous bases that can be found in DNA can be grouped into two different categories. The first category is Adenine and Guanine. The second category is going to be pyrimidine which will be composed of Cytosine and Thymine. Some people would refer to nitrogenous bases as nucleobases which means that they contain biological compounds that are meant to create nucleosides.

They are also the interior of the DNA double helix. Nucleosides, on the other hand, come from nucleotides. These monomers will be used to create different nucleic acids. Take note that the nitrogenous base will just have the same chemical properties as the base.

There are two nitrogenous bases of the purine type, which are guanine and adenine. Guanine is part of the nucleotides in RNA and DNA. The nucleotides that have guanine have chemical reactions that are very powerful. These reactions are responsible for making signals inside the cell. Guanine can also be found in other substances, such as cosmetics and in bird droppings.

Adenine has two functions, which will vary upon where the adenine is found. In the DNA, the adenine will stick to the thymine. This will strengthen the nucleic acid structures. In the RNA, the adenine is used for the purpose of protein synthesis in cytoplasm.

There are two correct answers to this question. The first is Adenine. It sticks to thymine. It sticks to it along with two other hydrogen bonds. They help strengthen the nucleic acid structures. When adenine is in RNA, the adenine is stuck to uracil.

The second nitrogenous base that is of the purine type is guanine. The chemical formula of guanine is C5H5N5O. It is also present in DNA and RNA. It was first discovered in 1844 by the scientist Julius Bodo Unger. From there, it was first synthesized in the 1900s. It can be found in guano and fish scales.

Purines and pyrimidines are the two groups of nitrogenous bases that are comprised of sugar and phosphate chain. A purine is a heterocyclic pungent organic mixture that entails two rings. It is water-soluble, as purine gives its name to the broader class of molecules, including substituted purines and tautomers.

They are the most commonly occurring nitrogen-containing heterocycles. Nitrogenous bases include nucleotide hydrolysis, which generates two types of substances from the heterocyclic ring’s purine and pyrimidine bases.

There are four distinct types of nitrogenous cores discovered in DNA. These include adenine, thymine, cytosine, and guanine. The materials made up of the nitrogenous purine bases include adenine and guanine, and the pyrimidines include thymine and cytosine.

Guanine and adenine could be the right answer.
