Concept of hybrid molecules: When double strand DNA is steamed to a temperature exceed the melting temperature (Tm), it will separate into 2 single strands DNA due to breaks of H bonds. If the reaction temperature is then decreased slowly plus other appropriate experimental conditions, these ssDNA will pair again. This phenomenon is called the hybridization of molecules. Characteristic of the hybrid molecules: Specificity, the re-pairing occurs only between two complementary sequences.

The phenomenon of the transformation of proteins into amyloid-fibrils is of interest, firstly, because it is closely connected to the so-called conformational diseases, many of which are hitherto incurable, and secondly, because it remains to be explained in physical terms (energetically and structurally). The process leads to fibrous aggregates in the form of extracellular amyloid plaques, neuro-fibrillary tangles and other intracytoplasmic or intranuclear inclusions.

Cells must be able to process multiple information in parallel and, more-over, they must also be able to combine this information in order to trigger the appropriate response. This is achieved by wiring signalling pathways such that they can interact with each other, a phenomenon often called crosstalk.
