ABSTRACT

The processes of life are carried out at the molecular level by a few distinct categories of biomolecules. The DNA sequences, which constitute the genome of an organism, can be thought of as blueprints for making proteins, which constitute most of the “machinery of life”. The translation from DNA to proteins is carried out via intermediate copies in the form of RNA sequences. Membranes made up of lipid bilayers provide structural separation for cells and other organelles. Short poly-peptide chains, made up of the same material as proteins, serve as messengers between cells. Finally, of course, there are a wide variety of molecules being created, transported, and consumed by the organism by means of the proteins.
