Adenine and guanine molecules are two of the four nitrogenous bases that help make up the structure of DNA. They are also known as "purine" bases because they have a double ring structure. The purine bases are extremely important in DNA formation and they specifically pair up with the other two nitrogenous bases, known as the "pyrimidine" bases. Adenine molecules will always pair with thymine molecules and guanine molecules will always pair with cytosine.

Bases with double C-N rings?
Adenine & Guanine
What are the 4 different bases in DNA?
A-Adenine C-Cytosine T-thymine G-guanine
What two purines are in DNA?
Adenine and guanine .
What are the four nitrogen bases of RNA?
Adenine, Uracil, Cytosine and Guanine; (adenine bonds with uracil) and (cytosine bonds with guanine). Thymine DOES NOT appear in the sequence; for instance if the DNA strand starts: A G C T, the Rna would be: A --> U G --> C C --> G T --> A.
Which two nitrogenous bases are purines?
Adenine and guanine.
How many rings are present in adenine and guanine?
2 rings each .
Which nitrogenous base is composed of two rings?
the nitrogenous base which has double ring structure is purine.it consist two bases adenine and guanine;
Bases with double C-N rings?
Adenine & Guanine
What two bases are in purines?
Adenine and guanine are the two purines bases present in DNA.Two purines in DNA are adenine and guanine.
What are the 4 different bases in DNA?
A-Adenine C-Cytosine T-thymine G-guanine
What two purines are in DNA?
Adenine and guanine .
What are the four nitrogen bases of RNA?
Adenine, Uracil, Cytosine and Guanine; (adenine bonds with uracil) and (cytosine bonds with guanine). Thymine DOES NOT appear in the sequence; for instance if the DNA strand starts: A G C T, the Rna would be: A --> U G --> C C --> G T --> A.
Which two nitrogenous bases are purines?
Adenine and guanine.
Is thymine single ringed?
1, thymine and cytosine are pyrimidines (1 ring). Purines (adenine and guanine) have 2 rings.
What are four nitrogen bases on DNA?
The four nitrogenouse bases found in DNA are adenine, thymine, cytosine, and guanine. When they are paired up it's always adenine to thymine, guanine to cytosine, thymine to adenine, and cytosine to guanine. They can't be mismatched such as adenine to guanine or cytosine
How many different nitrogen bases are there?
4 in DNA: Thymine, Cytocine, Guanine, and Adenine, and 4 in RNA: Adenine, Guanine, Cytosine, and Uracil.
Name the four nitrogen bases?
There are 4 nitrogenous bases found in DNA; Cytosine, Adenine, Guanine, and Thymine. Cytosine pairs with Guanine, and Thymine pairs with Adenine. *In RNA, Uracil replaces Thymine, therefore Adenine pairs with Uracil, in RNA.*
