Ethnographic Approaches to Race, Genetics
In recent years, there has been a technological advance and commercial boom in genetic technologies and projects, including a renewed scientific interest in the biological status and genetic constitution of race. This article provides an overview of sociological approaches to the study of race and genetics, and argues that these analyses should pay detailed critical attention to laypeople’s eng...
متن کاملGenomic approaches to the genetics of alcoholism.
When studying complex diseases such as alcoholism that develop as a result of numerous genetic and environmental factors, researchers can use the sequence data that have become available both for the human and for animal genomes. For these analyses, investigators are being aided by efforts to identify and characterize functionally relevant DNA sequences in the entire genomic DNA sequence--a pro...
متن کاملGenetics and new approaches to cancer therapy.
The past two decades have been golden years for the genetics of cancer. It has become clear through the work of countless laboratory groups that both inherited and sporadic cancers arise through defects or misregulations of their genomes. Several dozen dominantly acting oncogenes have been identified, shown to be deregulated in human tumors and to positively influence one or another aspect of t...
متن کاملCommentary: three approaches to drug abuse genetics.
Several different lines of evidence now suggest substantial genetic influences on inter-individual differences in vulnerability to drug abuse (Uhl et al. 1994). The three proposed studies described by Comings, by Tsuang and Lyons, and by McGue, Lykken, and Iacono each approach issues relating to genetics of drug abuse vulnerability in ways that are distinctive and interesting. Moreover they app...
متن کاملForward genetics in mammalian cells: functional approaches to gene discovery.
Definitive proof of function in biological systems requires genetic analysis. Only when the loss of a particular protein corresponds to the loss of a specific function can one be sure that the protein truly affects the function. Changing the pattern of gene expression through random mutagenesis or by introducing expression libraries, followed by selection of mutant or variant cells and identifi...
