The large bases that have two carbon-nitrogen rings are called purines.
Adenine & Guanine
purines and pyrimidines
Adenine & Guanine
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.
Plastids, or small rings of DNA that can be exchanged between bacteria. Rather than containing an entire genome, they just contain certain genes-often useful ones for resistance to antibiotics, etc.
You could tell the age of the tree by the rings by counting the rings.The ring equal one year. example: If 500 rings are in the trunk then it will be 500 years.
In DNA, the actual nitrogenous base rings make up the "ladder" while the "sides" are made from alternating deoxyribose and phosphate groups.
These rings are known as pyrimidines.
THC is a large molecule containing many aromatic rings. It does not have a common VSEPR shape, but it mostly sits in the same plane.

There is no planet with large rings and icy rocks. Saturn has rings, but it is not a rocky planet - it is a gas giant.
Saturn has 7 rings named from a to g see that's seven

it was about 63 rings and 4 large rings.
The category of nitrogen bases that consists of two rings is the purines.A nitrogenous base is an organic compound that owes its property as a base to the lone pair of electrons of a nitrogen atom. Notable nitrogenous bases include purines.Purines have two fused rings of carbon and nitrogen atoms.

Saturn has a very large system of rings around it.
