Adenine & Guanine

Purines are the bases that contain double C-N rings. Adenine and guanine are the two purine bases found in DNA and RNA. They play a key role in forming base pairs with pyrimidine bases to create the rungs of the DNA double helix.
The large bases that have two carbon-nitrogen rings are called purines.
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.
Double ring bases are typically used in chemistry to stabilize and support apparatus like flasks or condensers. They consist of two concentric metal rings, with the outer ring serving as a stand and the inner ring used to hold the equipment. This setup provides added stability and support for the apparatus during experiments.
There are 12 pairs of cranial nerves connected to the brain. These nerves control various functions such as sensation, movement, and balance, and they are numbered based on their location in the brain.
adenine and guanine are double ringed bases, that bond with thymine and cytosine (mono ringed bases). adenine bonds with thymine (double connection, whereas guanine bonds with cytosine (triple connection)
