Structural View of Biology


The major molecules of protein synthesis, from DNA to RNA to ribosomes to folded proteins, are available in the PDB archive. Proteins are built in several steps in all living organisms. The blueprint for each protein is stored in the genome, encoded in strands of DNA. This information is transcribed into an RNA copy, which is then used to construct the protein chain. After the chain is synthesized, it may be modified with special chemical groups, chaperoned into its proper folded shape, and ultimately destroyed when it is not needed any longer.

Structure of Nucleic Acids

Nucleic acids carry genetic information in the sequence of nucleotides.

DNA Maintenance

The DNA genome must last the life of a cell, and must be passed on to future generations with no mistakes.

Replication

A complete copy of the DNA genome is constructed every time a cell divides.

Transcription

The genetic information in DNA is used to build RNA strands.

Translation

Proteins are built by ribosomes, based on the genetic information carried by RNA strands.

Protein Folding - Modification - Degradation

Cells carefully manage their proteins from synthesis to disposal.
