replication

1. A turning back of a part so as to form a duplication.

2. (Science: molecular biology) The process of duplicating or reproducing, as the replication of an exact copy of a polynucleotide strand of dNA or rNA.

3.Replication can be either continuous or discontinuous Origin: L. Replicatio = a fold backwards (genetics) the process whereby DNA makes a copy of itself before cell division.The synthesis of an exact copy of a structure from a template of the same structure.

... not living can evolve. Evolution is based on DNA mutations, viruses needs to be replicated, no matter, whether you call them alive or not. The replication is not perfect. What is so hard to understand about that? Perhaps you should think viruses as biological nanomachines: they are not quite ...

Re:

... activity, it's been selected so by the means of natural selection, and thus it is not complete random. If they needed better fidelity in replication or translation, they would carry enzymes that facilitate proofreading. The mutations are random, but not the rate of them. Of course you ...

Can a mutation reverse itself?

... If by during the duplicating of the DNA, the mutation is fixed, then all is good again. There are DNA repair mechanisms in place during DNA replication that this is usually the case. It is only when the mutation is in a place where it is stable enough to proceed thru all the repair mechanisms ...
