Adenine is an example of this category of nucleotides, Guanine is an example of this category of nucleotides, This type of nucleotide has a longer base, This is the opposite of a pyrimidine

|
These are formed between codons and anti-codons in ribosomes

|
|
These join together to form either RNA or DNA

Detailed explanation-1: -Purines (adenine and guanine) are two-carbon nitrogen ring bases while pyrimidines (cytosine and thymine) are one-carbon nitrogen ring bases. Also Read: Amino Acids.
Detailed explanation-2: -Adenine and guanine are purine bases. These are structures composed of a 5-sided and 6-sided ring. Cytosine and thymine are pyrimidines which are structures composed of a single six-sided ring. Adenine always binds to thymine, while cytosine and guanine always bind to one another.
Detailed explanation-3: -Because of their structural similarity, we usually refer the nine-member double rings adenine and guanine as purines, and six-member single-ring thymine, uracil, and cytosine are pyrimidines.
Detailed explanation-4: -The purine nucleotides, adenosine, adenosine diphosphate (ADP), and adenosine triphosphate (ATP), are autacoids that serve as neurotransmitters in addition to their well-known cellular functions as intermediates in energy pathways and mediators of enzymatic reactions or cofactors.
