About Gene profiling

Gene profiling is the measurement of the activity of thousands of genes at time or to create a complete picture of cellular function. Gene expression profiling is the determination of the pattern of genes expressed, at the level of transcription, under specific circumstances or in a specific cell to give a global picture of cellular function. In almost all cells in an organism contain the entire genome of the organism only a small subset of those genes is expressed as messenger RNA (mRNA) at any given time and their relative expression can be evaluated. Techniques which are involved in profiling include DNA microarray technology or sequenced-based techniques such as serial analysis of gene expression.
