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 cont…ain one carbon-ring while purines have two.
Purines- Adenine (A), and Guanine (G) Pyrimidines- Cytosine (C), Thymine (T), and Uracil (U)
Purine must pair with pyrimidine due to their sizes. One has a large double ring and the other one a small single ring. This makes pairing easy for them.
Thymine and Cytosine are the pyrimidine nucleotides of DNA, while Adenine and Guanine are the purine structures.
-Adenine and Guanine are purine. -Thymine, Cytosine and Uracil are pyrimidine.
The purines are Adenine and Guanine nucleotides; while the pyrimidines are Cytosine, Thymine - and Uracil in Rna - nucleotides. They are the 'beads' that make up the immense… chain of nucleotide bases in Dna. A, C, G, T & U: Adenine - represented by an A; Cytosine - represented by a C; Guanine - represented by a G; Thymine (Dna only) - represented by a T; and Uracil (Rna only) - represented by a U. A pyrimidine is a single ringed base. The three kinds are; Cytosine, Thymine (in Dna) and Uracil (only in Rna). A purine is a double ringed base. the two kinds are; Adenine and Guanine. Adenine pairs with Thymine in Dna - or Uracil in Rna; Guanine pairs with Cytosine in both Dna and Rna.
Purines are the larger nitrogen base, consisting of a five ring bonded to a six ring. Pyrimidines are the smaller nitrogen base, consisting of a six ring.
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.
The rungs of the ladder are pairs of 4 types of nitrogen bases. Two of the bases are purines - adenine and guanine. The pyrimidines are thymine and cytosine. The bases are kn…own by their coded letters A, G, T, C. These bases always bond in a certain way.

The three kinds are; thymine (DNA), Uracil (RNA), and cytosine.A purine is a double ringed base. the two kinds are; adenine and guanine. Adenine pairs with thymine in DNA or Uracil in RNA. Guanine pairs with Cytosine in both DNA and RNA
the difference it that purine is a nitrogenous base that has a double-ring structuer and pyrimidines is a nitrogenous base that has a single-string structure cnbwm
They are the nitrogen bases that are attached to RNA and DNA. In DNA, adenine and guanine are purines and thymine and cytosine are pyrimidines. In RNA, thymine is replaced by …pyrimidine uracil.
purine. I remember cytosine, guamine, and uracil are pyrimindine because the word pyrimidine makes me think of the word pryamid and there are THREE pyrimidines which spell th…e word CUT :) hope that helps :)
A nucleotide can consist of either a purine or pyrimidine. A nucleotide is composed of a phosphate group and a nucleoside (a pentose sugar and a nitrogenous base). However, …the nitrogenous base can either be a pyrimidine or a purine. It is a pyrimidine if the nucleotide is a cytosine (C), thymine (T), or uracil (U). It is a purine if the nucleotide is adenine (A) or guanine (G). Note that thymine is only found in DNA whereas uracil is only found in RNA.

Purines are the basic building blocks of DNA and RNA and are the bases of adenine and guanine: two of the 4 nucleotide bases in DNA. In easiest terms to describe the purine wi…thout using a drawing program is draw a benzene ring (6 member ring of carbons with double bonds every other bond). Then number the carbons 1-6. Replace carbon 1 and 3 with a carbon and attach a nitrogen bond to the 4 and 5 carbon. Off one of those nitrogen bonds add a double bond to a carbon. Then connect that C to the nitrogen bond you added off #4 carbon. This will be a 6 member ring with a 5 member ring attached. Pyrimidines are just the 6 member ring you made in the purine. It is called a 1 3 diazine ring. Pyrimidines are the basis of the other nucleic bases in DNA and RNA called cytosine, uracil, and thymine. Pyrimidines have much lower boiling points and molecular masses than purines.
