DNA MICROARRAYS Meaning and
Definition
-
DNA microarrays are powerful tools used in molecular biology and genetics to study gene expression and genetic variation on a large scale. Also known as DNA chips or gene chips, DNA microarrays consist of small, solid supports such as glass slides or silicon chips onto which thousands of DNA molecules are attached or printed in an organized pattern.
The DNA molecules on the microarray represent genes from a specific organism or genome, allowing researchers to analyze gene expression levels or detect sequence variations simultaneously for numerous genes. Each DNA spot on the microarray corresponds to a specific gene, and the intensity of the fluorescence signal emitted from each spot is proportional to the amount of mRNA or DNA bound to it.
DNA microarrays enable high-throughput analysis, as they can analyze thousands of genes in a single experiment, providing a snapshot of gene activity in a given tissue or organism. These arrays are utilized in various fields of research, including genomics, functional genomics, genetics, and personalized medicine.
By comparing gene expression patterns between different samples, scientists can gain insights into how genes are regulated, identify genes involved in disease processes, identify potential drug targets, and understand the effects of environmental changes on gene expression. DNA microarrays have revolutionized the field of molecular biology by allowing comprehensive analysis of gene expression, leading to advancements in our understanding of cellular processes and diseases.

Etymology of DNA MICROARRAYS
The word "DNA" stands for deoxyribonucleic acid, which is a molecule found in the cells of all living organisms. It is responsible for storing and transmitting genetic information. The abbreviation "DNA" was coined by Friedrich Miescher, a Swiss biochemist, in 1869.
The term "microarray" is a combination of two words: "micro" meaning small and "array" meaning arrangement or collection. The concept of microarrays originated in the field of electronics and refers to a collection of tiny electronic components organized in a grid pattern on a small surface. The term was later borrowed and applied to the field of molecular biology to describe a collection of thousands of DNA sequences that are immobilized onto a small solid surface, usually a glass slide or a silicon chip.
