purines
Thymine is a single-ringed nitrogenous base.
The two pyrimidines, cytosine and thymine, are composed of a single-ring structure containing carbon and nitrogen atoms. These nitrogenous bases are essential components of nucleotides in DNA and RNA molecules.
DNA is a double helix structure composed of two long strands made up of nucleotides. The nucleotides are made up of a sugar, a phosphate group, and a nitrogenous base. The nitrogenous bases adenine, thymine, cytosine, and guanine form complementary base pairs that hold the two strands of DNA together.
The base uracil is a nitrogenous base in RNA used for protein synthesis. It replaces Thymine from DNA.
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.

Thymine is a single-ringed nitrogenous base.
These two terms are {practically} synonymous; they both have the same meaning.
double helix composed of two strands that are twisted together. The strands are made up of nucleotides which consist of a sugar, phosphate group, and a nitrogenous base. This structure allows DNA to store and transmit genetic information.

The base uracil is a nitrogenous base in RNA used for protein synthesis. It replaces Thymine from DNA.
The nitrogenous bases with two rings are called purines. In DNA and RNA, the two purines are adenine (A) and guanine (G). These bases are larger than the single-ring structures known as pyrimidines, which include cytosine (C), thymine (T), and uracil (U).
First off - it is important to understand that a nucleotide (the monomer of DNA) is composed of 3 things: a sugar, a phosphate group, and a nitrogenous base. Next - understand that the "backbone" of DNA is composed of the sugars and phosphates. That leaves you with nitrogenous bases. Hydrogen bonds form between the nitrogenous bases off opposite strands in the double helix. THIS is what holds the double helix together.
hydrogen bonds between complementary nitrogenous bases.
Mars has two prominent rings that are composed of primarily dust and rocks. These rings are relatively small compared to other planets' rings, such as those around Saturn.
