Discusses the characteristics of and differences between nucleosides and nucleotides as well as the significance of each in medicine.

Purines and pyrimidines are nucleotides. Their properties are described here and their differences are highlighted. Includes examples of each.

A stop codon is a nucleotide triplet in messenger RNA that signals the end of a protein during the translation process. Read about how this works, the different types of stop codons, and how a mutation can sometimes occur.

A start codon is a nucleotide triplet in a genetic sequence that occurs at the start of a protein's synthesis. Read about how this works and how a mutation can sometimes occur.
