Why only adenine guanine cytosine thymine and uracil are only considered as the basic units of DNA why not other purines and pyramidines?
You question dosent really make sence, but if you are asking why are they not Purines and Pyramidines...They are Adenine and Guanine are Purines, and then you can realise that Thymine Cytosine and Uracil are all Pyramidines.
If you are asking why are they only considered as purines and prymidines they are not there a many different types of Purines and Pyramidines but because when you study Biology and DNA is a topic that you cover frequently, they are noted but an example of a Purine is Uric Acid (essentially a product when it a Purine is broken down but still considered as a Purine).
Hope this is helpful...
What else can I help you with?
Name the four nitrogen bases?
There are 4 nitrogenous bases found in DNA; Cytosine, Adenine, Guanine, and Thymine. Cytosine pairs with Guanine, and Thymine pairs with Adenine. *In RNA, Uracil replaces Thymine, therefore Adenine pairs with Uracil, in RNA.*
What are the 4 different bases in DNA?
A-Adenine C-Cytosine T-thymine G-guanine
What are four nitrogen bases on DNA?
The four nitrogenouse bases found in DNA are adenine, thymine, cytosine, and guanine. When they are paired up it's always adenine to thymine, guanine to cytosine, thymine to adenine, and cytosine to guanine. They can't be mismatched such as adenine to guanine or cytosine
What are the names of 4 N bases in DNA?
Adenine, Thymine, Guanine, Cytosine.
What are the 4 bases in RNA?
The four bases that make up RNA are: * Adenine (A) * Cytosine (C) * Guanine (G) * Uracil (U)
What are the nitrogenous bases for DNA and RNA?
Pyrimidines, which include cytosine, thymine and uracil.andPurines, which include adenine and guanine

What are the RNA nitrogen bases?
Adenine, guanine, cytosine and uracil ( which stands in for thymine ).
What is the pairing arrangement of the nitrogen base?
the pairing is adanine with thymine and guanine with cytosine. the pairing is adanine with thymine and guanine with cytosine.
What bases are found in DNA?
Adenine, Thymine, Guanine, and Cytosine
What are the nitrogenous base pairing rule?
adenine bonds to thymine cytosine bonds to guanine. (In RNA adenine bonds to uracil)
What are the four kinds of nucleotides?
In DNA: adenine, guanine, cytosine, thymine. In RNA: adenine, guanine, cytosine and uracil.
What are the names of 4 N bases in DNA?
Adenine, Thymine, Guanine, Cytosine.
What are bases in DNA and RNA?
DNA Adenine with Thymine, Guanine with Cytosine RNA Adenine with Uracil, Guanine with Cytosine
The nitrogen base that pairs with guanine?
In nucleic acids, the base that pairs with guanine is cytosine.
