The DNA bases adenine and guanine have one nitrogen and carbon atom containing ring in their structure. These bases are known as __________.
purines
The DNA bases adenine and guanine, which have one nitrogen and carbon atom containing ring in their structure, are known as purines.
To find the answer to this question, you can start by understanding the structure of DNA and the different types of bases it contains. DNA is made up of four different bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
Adenine and guanine are classified as purines, which are larger nitrogenous bases that contain a double-ring structure. In contrast, cytosine and thymine are classified as pyrimidines, which are smaller nitrogenous bases that contain a single-ring structure.
By studying the molecular structures of these bases, you can identify that adenine and guanine have a double-ring structure with one nitrogen and carbon atom-containing ring. Therefore, they are referred to as purines.
