What and what are two classes of nitrogenous bases?
purines and pyramidines.
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 are pyrimadines an purines?
what is the difference between a purine and pyrimadine
What are the three molecules of a nucleotide?
A nucleotide is composed of a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil), a ribose sugar (ribose or deoxyribose), and a number of phosphates (1 to 3).
What are you two purines in DNA?
Adenine and guanine are the two purines in the DNA and thymine and cytosine are two pyrimidines.

What are pyrimadines an purines?
what is the difference between a purine and pyrimadine
How do purines differ from pyrimidines?
Purines and pyrimidines are the building blocks of nucleic acids. The difference between purines and pyrimidines is in the number of carbon-rings present. Pyrimidines contain one carbon-ring while purines have two.
What is the difference between a purines and pyrimidines?
A purine has a double ring, while a pyrimidine has a single ring. Also purines are adenine and guanine, and the pyrimidines are thymine and cytosine.
How many rings do pyramidines have?
1
Can purines pair with other purines?
No. The physical structure does not allow purines to pair with other purines. Purines can only be paired with Pyrimidines.
What is the major difference between nucleotides of deoxyribonuleic acid and ribonucleic acid?
DNA: Purines: Adenine, Guanine Pyrimidines: Thymine, Cytosine RNA uses uracil instead of thymine Hope this helps
What to purines are in DNA?
adenine and guanine are the two purines
Which one is purines and pyrimidines are bigger?
Purines because purines have two rings where as pyrimidines have only one ring.
What nitrogenous bases are pyramidines?
i) thymine ii) cytosine and iii) - in Rna only is found - uracil.
What are the nitrogenous bases for DNA and RNA?
Pyrimidines, which include cytosine, thymine and uracil.andPurines, which include adenine and guanine
