What are the substances represented by the letters A and G called?
The nitrogenous substances A and G are purines (double rings).
What belong to the class of nitrogenous bases called pyrimidines?
There are three; cytosine, thymine and uracil.
What are the four bases found in DNA?
adenine----The four nitrogenous bases that comprise DNA are adenine, guanine, thymine, and cytosine. there are four kinds of nitrogenous bases in dna. two of the nitrogenous bases, adenine and guanine,belong to a group of compounds known as purines. the remaining two bases, cytosine and thymine, are know as pyrimidines. Adenine pairs up with thymine, and cytosine pairs up with guanine. Humans also use a fifth base in RNA called uracil. In the case of RNA, thymine is replaced by uracil and other three bases remains the same. All of these bases are attached to the sugar and phosphate. The double helix maintains a constant width because purines always face pyrimidines in the complementary A-T and G-C pairs. And they are all connected by a phosphorous base. A-T; G-C The phosphorous base can be broken for DNA replication purposes.
Name for large bases containing two carbon-nitrogen rings?
The large bases that have two carbon-nitrogen rings are called purines.
What is a pentose joined to a nitrogenous base and a phosphate group?
A pentose joined to a nitrogenous base and a phosphate group is called anucleotide. Nucleotides are building blocks of nucleic acids.

what belongs to the class of nitrogenous bases called purines
Nitrogenous bases called purines?
Guanine and Adenosine
What and what belong to the class nitrogenous base called pyrimidines?
Purines and pyrimidines.purines contain adenine,guanine,hypoxanthine and xanthine.pyrimidines contain uracil,thymine,cytosine,orotic acid
How many nitrogenous bases are there What are they called?
Four, out of whish 2 purines and two pyremidines
What are the substances represented by the letters A and G called?
The nitrogenous substances A and G are purines (double rings).
What are the two nitrogenous called purines and pyridine?
The two purines are adenine and guanine. The two pyrimidines are thymine and cytosine. Uracil (only in RNA) is also a pyrimidine.
What is test for purines?
The two DNA bases Adenin and Guanine belong to the group called Purines.
What and what belong to the class of nitrogenous bases called pyrimidnes?
Plato users D. Thymine, cytosine
Nitrogen bases with only 1 ring are called?
Purines
Which two nitrogenous bases are bound by three hydrogen bonds?
Theyre pyrimidines Because Adenine and guanine both have two and cytosine and thymine have one.
What are the two bases in DNA that are purines called?
Adenine and guanine are both double ringed purines.
