The Ethics of Genetic Engineering

Journal of Applied Philosophy, 1996
ABSTRACT The aim of this article is to determine whether genetic engineering is ever acceptable. The prominent arguments which have been put forward by the opponents of genetic engineering are examined and evaluated. The arguments ‘we should not interfere with nature’, ‘we should not alter the genetic constitution of organisms’, and ‘we should not ...

Genetic engineering for haemophilia A

Expert Opinion on Biological Therapy, 2006
At first sight, haemophilia A would appear to be an ideal candidate for treatment by gene therapy. There is a single gene defect; cells in different parts of the body, but especially the liver, produce Factor VIII, and only 5% of normal levels of Factor VIII are necessary to prevent the serious symptoms of bleeding.

Politics and Genetic Engineering

Politics and the Life Sciences, 1992
THE PURPOSE OF THIS short note is to update readers on recent developments in, and political implications of, genetic engineering, a critical tool in the expanding field of biotechnology. Based on new understanding of the mechanisms of DNA, molecular biologists are now able to chemically cut genes or sets of genes from one organism and splice them into

ENGINEERING GENETIC INJUSTICE

Bioethics, 2005
ABSTRACTIn their jointly written book, From Chance to Choice: Genetics and Justice, Allen Buchanan, Dan Brock, Norman Daniels and Daniel Wikler defend ‘the development and deployment of genetic intervention technologies . . .’, including genetic enhancements, against charges that they exacerbate injustice.

Evolution and Genetic Engineering

2013
A 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.

Genetic engineering Techniques

1997
This chapter gives a brief introduction to the biotechnological techniques which have been used for transforming genomes of plants and plastids. The aim of the engineering methods is to transfer a piece of a species-alien DNA molecule into the genome of a selected species providing the species with a new function or an altered function.

human genetic engineering

Technology in Society, 1984
Abstract The author addresses the new ethical and conceptual uncertainties posed by the application of gene-splicing techniques to human beings, an application of technology that raises complex ethical and social public policy issues. The author reviews the advances in the medical uses of gene-splicing, and addresses their consequences on (1) human ...

Engineering of the genetic code

Current Opinion in Biotechnology
The genetic code is a universally conserved mechanism that translates genetic information into proteins, consisting of 64 codons formed by four nucleotide bases. With a few exceptions, the genetic code universally encodes 20 canonical amino acids (AAs) and three stop signals, with many AAs represented by multiple codons.

Genetic engineering of immunotoxins

1988
Genetic engineering offers many advantages for the 1) production of immunotoxins (ITs) and 2) design of more effective reagents. In Chapter 9, J.R. Murphy discusses the use of genetic engineering to link genes together resulting in chimeric proteins. This review covers the first applications of genetic engineering technology to improve ITs by studying ...

Genetic engineering of the chloroplast

Biochimie, 2000
Transformation of the plastid genome has a number of inherent advantages for the engineering of gene expression in plants. These advantages include: 10-50 times higher transgene expression levels; the absence of gene silencing and position effect variation; the ability to express polycistronic messages from a single promoter; uniparental plastid gene ...
