None. Rings are a custom, not a legal requirement.
Two. All prismatic shapes have two bases.
No.But is does have two parallel and identical bases.
Two: the two hexagonal faces are normally called the bases.
No it has two bases which are parallel.
Adenine, Thymine, Guanine and Cytosine.

The large bases that have two carbon-nitrogen rings are called purines.
purines
pyrimides
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.
Nitrogen bases are made up of hydrogen bonds, phosphate, and sugar
there are double rings in the purine bases and there is only a single ring in the pyrimidine base.
DNA is composed of phosphate, proteins, nitogenous bases, sugar. they all maintain the structure of the DNA and are responsible for replicating the DNA accurately during replication.. for example; nitrogenous bases are correctly base paired i. e. A with T and G with C.
the nitrogenous base which has double ring structure is purine.it consist two bases adenine and guanine;
Adenine and guanine molecules are two of the four nitrogenous bases that help make up the structure of DNA. They are also known as "purine" bases because they have a double ring structure. The purine bases are extremely important in DNA formation and they specifically pair up with the other two nitrogenous bases, known as the "pyrimidine" bases. Adenine molecules will always pair with thymine molecules and guanine molecules will always pair with cytosine.
