What and what are two classes of nitrogenous bases?
The two classes of nitrogenous bases are purines and pyrimidines. Purines include adenine and guanine, while pyrimidines include cytosine, thymine, and uracil.
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?
Pyrimidines (cytosine, thymine, uracil) are nitrogenous bases with a single-ring structure found in DNA and RNA. Purines (adenine, guanine) are nitrogenous bases with a double-ring structure also found in DNA and RNA. They form the building blocks for nucleic acids.
What is the the difference between purines and pyrimidines?
Purine- double-ringed ex: adenine and guanine Pyrimidines- single-ringed ex: cytosine and thymine
What are the two Purines in DNA?
two of the bases are purines- adenine and guanine.

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
What is the difference between the four types of nitrogenous bases?
The four types of nitrogenous bases are adenine (A), thymine (T), guanine (G), and cytosine (C). Adenine and guanine are purines, while thymine and cytosine are pyrimidines. Purines have a double-ring structure, while pyrimidines have a single-ring structure. This structural difference is important in how the bases pair with each other in DNA and RNA molecules.
What are pyrimadines an purines?
Pyrimidines (cytosine, thymine, uracil) are nitrogenous bases with a single-ring structure found in DNA and RNA. Purines (adenine, guanine) are nitrogenous bases with a double-ring structure also found in DNA and RNA. They form the building blocks for nucleic acids.
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
Account for the formation of precipitate in the test for purines.?
The formation of precipitate in the test for purines is used because purines cannot be found in human DNA unless a test is performed to find their waste or byproducts. Purines cannot be tested for without boiling in alcohol to break them down.
Can purines pair with other purines?
No, purines cannot pair with other purines in DNA or RNA. Purines always pair with pyrimidines through complementary base pairing to maintain the double-stranded structure of DNA. In DNA, adenine (a purine) pairs with thymine (a pyrimidine) and guanine (a purine) pairs with cytosine (a pyrimidine).
What are the nitrogenous bases for DNA and RNA?
Pyrimidines, which include cytosine, thymine and uracil.andPurines, which include adenine and guanine
