| Protein | Class Protein - * This class represents the end-products of genetic processes of translation and transcription -- the proteins. While a protein's primary structure (its amino acid sequence) is ably represented as a Sequence object, its secondary and tertiary structures are not. This is the main rationale for creating a separate Protein class. |
