Evolution and Genetic Engineering
2013A cell’s genotype represents the cell’s genetic potential, whereas its phenotype represents the expression of a culture’s potential. The genotype of a cell can be altered by mutations. Mutations may be selectable or unselectable . The rate of mutation can be enhanced by the addition of chemicals called mutagens or by radiation.

Entropy of the genetic information and evolution
Origins of Life, 1974The entropy of the amino acid sequences coded by DNA is considered as a measure of diversity of variety of proteins, and is taken as a measure of evolution. The DNA or m-RNA sequence is considered as a stationary second-order Markov chain composed of four kinds of bases.

On the Evolution of Primitive Genetic Codes
Origins of life and evolution of the biosphere, 2003The primordial genetic code probably has been a drastically simplified ancestor of the canonical code that is used by contemporary cells. In order to understand how the present-day code came about we first need to explain how the language of the building plan can change without destroying the encoded information.

Evolution of the genetic apparatus
Journal of Molecular Biology, 1968Abstract It is argued that the evolution of the genetic apparatus must have required the abiotic formation of macromolecules capable of residue-by-residue replication. This suggests that polynucleotides were present even in the most primitive ancestors of contemporary organisms.
