Human genome and cloning: perspectives and questions on man

Abstract

Genome is defined as the global set of genetic information exists in the DNA molecules of the initial cell nucleus (zygote), and that remains unchanged in every cell of an individual. Universally valid, we can say that human life begins at the moment of fertilization, the zygote and that there is a complete program of development of a new human being with its own identity which is the same from conception to death. Everything that happens after is the fulfillment of that program, differential gene expression in space and time. The program will produce cellular differentiation of tissues and organs during embryonic development and the individual's life, at all stages of development, from fetus to adult. In the double dimension of biological development, spatial and temporal can not speak or partial identities or successive.
