COMPARATIVE GENOMIC HYBRIDIZATION (CGH)Comparative genomic hybridization is a technique to study changes in copy number of DNA. Classical CGH procedure consists in labeling DNA from the "test" patient" with a particular fluorescent dye that emits green light, while DNA from a normal individual serves as...

Serial analysis of gene expression (SAGE)SAGE is based on the principle that every gene can be identified by a unique tag located near the 3'-end of its mRNA. As there are 4 nitrogen bases A, T, G and C, a 10 bp tag gives us...

Subtractive hybridizationSubtractive hybridization (SH) is a technique which is used to determine the difference between two genomes, i.e. if two DNA samples are otherwise identical except for a region that has been deleted (as is common in several cancers) or added (as in case...

On biological determinism and genetic inheritance there are a number of ways to approach the topic. Most often the matter is addressed empirically. The idea is of one's being entirely vested in physicality. There is no criticism in that approach, however the real topic is...

Stem cell research, the greatest debate amongst humanity. Do we allow it? or do we prohibit it? I hadn't originally even heard of the concept until I heard about Christopher Reeve looking at furthering the research to find a cure for his paralysis. After looking...

Spring is coming and we will soon become a temporary home to umpteen species of wild bird migrants, flying in from across the world, and yes, some of them may be carrying avian influenza, commonly known as bird flu. Over the coming months, we may...

There is a general fear regarding the use of stem cells in research. People believe that stem cell research includes killing of embryos, thus reject this amazing and promising technology.Let's think clearly: Stem cells are cells coming from a fertilized ovum, a few days...
