Discovery a memory system in cell which is not the DNA

[Hector3000]

Few days ago it has been published a paper in the format of new scientific theory in "Frontiers in Molecular biosciences", entitled "Elements of the cellular metabolic structure", in which the main finding is the discovery of a new biochemical system (the CMS) with the capacity to store molecular information.

 

CMS exhibits two essential dynamic mechanisms. The first one occurs at the level d metabolic networks. The second mechanism occurs at the post-translational modulation level.

 

According to this published dualistic theory of the cell hereditary information, cells exhibit two systems capable of storing molecular information, a dynamic, flexible and adaptive system: the CMS (metabolic memory), and an essentially conservative structural system: the DNA (genetic memory).

 

The original paper is:

This theory represents a paradigm shift in biology?
