Abstract

Genome n. [gene plus chromosome] the complete set of chromosomes containing all of the genes of an organism. For man this set of 46 per cell stretches to a 6 foot strand of DNA. Within this string of 3 billion nucleotide bases are 100,000 genes. Utilizing a 4 letter alphabet (Adenine, Guanine, Cytosine, Thymine), genes provide the blueprint for the amino acid sequence of structural protein (cell membrane, connective tissue, etc) or functional protein (hormones, enzymes, transmitters, etc). DNA replication guarantees exact gene copies and chromosome meiosis and crossing over guarantees varied gene combinations. This forms the basis for the similarity and the diversity of all of humankind: the similarity needed to perpetuate successful genes and the diversity needed for genes to respond to the weeding out process of evolution.

[A separation of public health ethics from medical ethics].

Until now there are only a few approaches in the German-speaking realm to establish an explicit ethical framework for moral issues of public health--although a need for public health ethics in times of SARS and avian flu is obvious. One deficit of the discussion so far is that there is no systematic separation of medical ethics and public health ethics. Thus, the core and interdisciplinary focus of public health is often not met. However, to frame discussions of moral issues within a specific public health ethics framework seems to be fruitful. This paper deals with the conceptual differences of medical ethics and public health ethics. The discussion helps both applied ethical discourses to sharpen their focus and strengthen their appeal. The author develops and presents a conceptual and normative frame for public health ethics and offers a concise set of ethical principles for the discussion of moral challenges in public health.
