purines are double ringed nitrogenous bases of DNA and RNA including adenine and guanine. the three others are cytosine and thymine( uracil is present instead of thymine in RNA) are pyrimidines.

What molecules make up the rungs of a DNa ladder?
purines, pyrimidines, nucleotides and nitrogen bases.
Which nucleotide are purines and which are pyrimidine?
Thymine and Cytosine are the pyrimidine nucleotides of DNA, while Adenine and Guanine are the purine structures.
Which of the nitrogenous bases is the bulkiest?
Nitrogenous bases are used in the synthesis of nucleotides such as DNA and RNA. The bulkiest bases are the purines, guanine and adenine.
Adenine and guanine are what?
Adenine and Guanine arenucleic acids. They are found in DNA and RNA. In DNA Adenine bonds with another nucleic acid called Thymine and Guanine bonds with Cytosine. In RNA Adenine bonds with Uracil (only found in RNA) and Guanine still bonds with Cytosine. Adenine and quanine are : Purines, Pyrimidines
In DNA molecules nucleotides bond together according to the nitrogenous bases Which of the following correctly describes how nitrogenous bases bond together?
Purines bond to pyrimidines
What nucleotide is a double ringed molecule?
Purines are nucleotides with a double ringed structure.Adenosine and Guanine are purines
One of two purines used as a nitrogen base in nucleotides?
adenine
Which RNA and DNA nucleotides are purines?
The purines adenine and guanine are two of the four nitrogen bases in DNA. There are many other purines that are found in nature, but not in DNA.
What molecules make up the rungs of a DNa ladder?
purines, pyrimidines, nucleotides and nitrogen bases.
Purines and pyrimidines are?
Purines and pyrimidines are nitrogen bases found in DNA and RNA .They are nitrogen containing heterocyclic compounds .Purines are large double ringed while pyrimidines are small single ringed .
Addenine and guanine are single-ringed purines?
Adenine and Guanine are just purines (the other nucleotides are pyrimidines), and these have one 6-parts ring with 3-parts ring attached.
Which nucleotide are purines and which are pyrimidine?
Thymine and Cytosine are the pyrimidine nucleotides of DNA, while Adenine and Guanine are the purine structures.
Which of the nitrogenous bases is the bulkiest?
Nitrogenous bases are used in the synthesis of nucleotides such as DNA and RNA. The bulkiest bases are the purines, guanine and adenine.
Uric acid is formed by the breakdown of?
Purines. When cells animal or plant, die and are broken down Uric acid is the chemical formed when purines have been broken down completely.
What are the purines for DNA?
Purines are two of the four bases of nucleotides that make up DNA sequences. They are guanine and adenine, and are most often represented by the letters G and A.
Which nucleotides are pyrimidines?
Remember: Pure As Gold--- purines are arginine and guanine so, pyrimidines must be thymine and cytosine FREEGAZA.ORG
Adenine and guanine are what?
Adenine and Guanine arenucleic acids. They are found in DNA and RNA. In DNA Adenine bonds with another nucleic acid called Thymine and Guanine bonds with Cytosine. In RNA Adenine bonds with Uracil (only found in RNA) and Guanine still bonds with Cytosine. Adenine and quanine are : Purines, Pyrimidines
