Nitrogenous bases with carbon and nitrogen atoms in two rings?
purines
What are the two nitrogen bases that are single ring structures?
Thymine is a single-ringed nitrogenous base.
What is contained in nucleic acids?
Nucleic acids are polynucleotides. They are composed of nucleotides, which join together through phospho-diester bonds, with forms the sugar-phosphate backbone of the nucleic acid, and also through hydrogen bonds, between two complementary nitrogenous bases (in the case of DNA).The nucleotides which make up nucleic acids are composed of the following: a phosphate group (PO4), a deoxyribose sugar (in DNA) or a ribose sugar (in RNA) and finally a nitrogenous base. In DNA the purine nitrogenous bases are: adenine and guanine. The pyrimidine nitrogenous bases are: thymine (which bonds with two hydrogen bonds to adenine) and cytosine (which bonds with guanine through three hydrogen bonds. In RNA uracil replaces thymine and there are no hydrogen bonds between the nitrogenous bases as RNA is a single stranded molecule.
What are the properties for DNA?
Key chemical property of DNA would have to be that it is composed of nucleotides held together by phosphodiester bonds, this nucleotides consist of a deoxyribose sugar, a phosphate group and a nitrogenous base, this nitrogenous base is the source of variation in a DNA molecule because the nitrogenous base can be either Adenine, Cytosine, Thymine or Guanine. In physical terms we can say that DNA has a double helix structure consisting of two anti parallel strands identical to each other joined together through the nitrogenous bases by hydrogen bonds, Adenine and Guanine are purines witch are double ringed structures and Cytosine and Thymine are pyrimidines witch are single ringed structures. A purine can only join with a pyrimidine, in DNA Adenine will bond with only thymine and cytosine with guanine.
How many rings does a purine have?
there are double rings in the purine bases and there is only a single ring in the pyrimidine base.
The category of nitrogen bases that consists of 2 rings is the?
The category of nitrogen bases that consists of two rings is the purines.A nitrogenous base is an organic compound that owes its property as a base to the lone pair of electrons of a nitrogen atom. Notable nitrogenous bases include purines.Purines have two fused rings of carbon and nitrogen atoms.
Nitrogenous bases with carbon and nitrogen atoms in two rings?
purines
What are the two nitrogen bases that are single ring structures?
Thymine is a single-ringed nitrogenous base.
What holds the two helixes in a DNA molecule together?
First off - it is important to understand that a nucleotide (the monomer of DNA) is composed of 3 things: a sugar, a phosphate group, and a nitrogenous base. Next - understand that the "backbone" of DNA is composed of the sugars and phosphates. That leaves you with nitrogenous bases. Hydrogen bonds form between the nitrogenous bases off opposite strands in the double helix. THIS is what holds the double helix together.
Is a nitrogenous base found in a nucleotide?
These two terms are {practically} synonymous; they both have the same meaning.

What are two parts of a nulceotide?
The pentose sugar (ribose in RNA, deoxyribose in DNA) and the phosphate group (these two form the sugar-phosphate backbone), and the nitrogenous base (A,C, G or T)
How many rings does a purine have?
there are double rings in the purine bases and there is only a single ring in the pyrimidine base.
What do the Olympic Rings look like?
The Olympic Rings are composed of five rings. There are three at the top - one blue, one black and one red. There are then a further two below this - one yellow and one green. The rings are all intertwined with each other. See the related link for an image of the Olympic Rings.
Is uracil a nitrogenous base?
Yes, the two nitrogen atoms in urcil function as hydrogen bond acceptors, so the molecule is basic.
What are the parts of the protein molecule?
DNA is composed of four nitrogenous bases: Adenine, Thymine, Guanine, and Cytosine. Adenine and Guanine are purine bases, while Cytosine and Thymine are pyrimidine bases. Since purine bases mate with pyrimidine bases, Adenine attaches to Thymine, while Guanine attaches to Cytosine. As DNA is turned into RNA, the nitrogenous base Thymine is replaced with the base Uracil.
