Evolution. Man takes a hand

Description

This program provides an explanation of how the twin techniques of gene splicing and cloning are helping to unravel the secrets of variation. Genetic engineering is altering the branching pattern of natural evolution-which proceeds by mutations within a species and sexual recombination within that species-into a network, in which genes are moved within the laboratory from any species to any other species. The program explains the irreversible and unforeseeable results of gene splicing and the scientific and governmental regulations under consideration-realistic scientific and moral questions, uninformed though highly imaginative hysteria. and the actual effects of cloning; it explains the sequences of DNA, how we are learning to read them, the masterminding message in the DNA of many different species, how cells activate only certain genes; and it follows the scientific and economic history of interferon and interleukin-2.
