TRACING THE ORIGIN OF CELL: The Replicator Molecules

                   TRACING THE ORIGIN OF CELL

Also viewing life from the point of ' replicator molecules' cell satisfies two fundamental factors which are protection from outside environment and confinement of the chemical activities. But before much will be spoken on this, we need to know what ' replicator molecules' are. A replicator molecule is one that has the ability to replicate itself, examples are DNA, RNA etc.

The protection giving to a cell is to help protect cell content and make complex molecules to be stable in a varying environment. Also, the confinement of biochemical activities is very important for the evolution of biocomplexity. Touching this two important aspect in viewing life from the point of ' replicator molecules', we can use the Enzymes for a major way of explanation. If the free floating molecules that code for enzymes are not resisted from the surrounding, the enzymes will undoubtedly benefit the neighbouring 'replicator molecules'.

 A situation whereby diffusion take place in a non- partioned life form is called " parasitism by default". But if the reverse becomes the case ,that is the molecule is enclosed in a membrane, then the enzymes coded will be available for the replicator molecules. This molecules will efficiently benefit from the enzymes it codes for, thereby increasing individuality and as well as accelerating natural selection.
