On 20 October 2009, this column addressed the topic of Y-DNA testing for genealogical purposes. This relatively new development in science holds revolutionary potential for genealogy, especially African-American research. The most recent issue of the National Genealogical Society Quarterly (Sep 2009) contains the case study of an African-American family where Y-DNA testing revealed direct male line European ancestry.[1]

The concept of gene transfer between cells first existed in bacteria; they are capable of at least four natural forms of genetic exchange. The genetic transfer technique is used very widely in basic research and applied biology. The delivery of DNA into an animal cell is a very established and fundamental procedure. It has become a very crucial tool for gene cloning, the study of gene function and the regulation and production of small amounts of recombinant proteins for analysis and verification. It helps to express the introduced genetic construct in the recipient cells or inactivate particular endogenous genes.

Surgical instruments need to be sterilized before use to prevent infection. WPI offers a vast range of steril

Gene transfer technique is used very frequently both in basic research and applied biology. The delivery of DNA into animal cells is a fundamental and fixed procedure. It has become anecessary tool for gene cloning, the study of gene function and regulation and the production of small amounts of recombinant proteins for analysis and verification. Gene transfer experiment helps to launch the genetic construct (or transgene) in the recipient cells or to disrupt or inactivate particular endogenous genes resulting in a loss of function. There are many utilizations of gene-transfer like large-scale commercial production of recombinant antibodies and vaccines and gene medicine or gene therapy. They range from the use of mammalian and insect cell cultures to transfer of DNA into human patients for the correction or prevention of disease.

Cardiac electrophysiology is the clinical study and diagnoses the electric activities going on in the heart. This subject field mainly includes the monitoring heart and detect the problems.

ECG Monitoring System that is cardiovascular electrophysiology device helps to study- Each heartbeat, a wave of cardiac muscle contraction pushes blood through the heart.

A transgenic animal is one whose genome has been altered by the transfer of a gene or genes from another species. In biomedical research, in the laboratory, transgenic animals are routinely used as models. Over 95 percent of those users are genetically modified rodents, predominantly mice. Transgenic animals have many Utilities which made them much superior to the normal animals. Utilities of Transgenic Animals: * During medical research, transgenic animals are mostly used to identify the functions of some specific factors in complex homeostatic systems. These can be through the over- or under-expression of a modified gene (the inserted transgene). * In the toxicology as the responsive test animals for the detection of toxicants. * In mammalian developmental genetics. * In molecular biology, this analysis of the regulation of the gene expression, make use of the informative evaluation of some specific genetic change, at the level of the whole animal. * While in the pharmaceutical industry, for the targeted production of pharmaceutical proteins, and during the drug production also on the product efficacy testing. * In biotechnology, as producers of specific proteins. * For the genetically engineered hormones to increase milk yield, meat production. * In the cloning procedures to reproduce some specific bloodlines in the genetic engineering of the livestock, and in the aquaculture that affects the modification of animal physiology and/or anatomy, * Developing animals specially created for use in xenografting.
