DNA microarray is simply a high-throughput molecular biology technique that is used to determine how genes work at any given point in time in a cell.It is used to study how genes are turned off or on in a cell. Similar to the traditional southern blotting technique (which is mainly used to detect the presence of a piece of DNA molecule in a sample), DNA microarray allows scientists to array. DNA Microarrays are one of the most effective invention ever developed. A DNA Microarray is a test that allows for the comparison of thousands of genes at once. Microarray technology uses chips with attached DNA sequences as probes for gene expression. Any DNA in the sample that is complementary to a probe sequence will become bound to the chip Introduction: A DNA microarray (also commonly known as gene or genome chip, DNA chip, or gene array) is a collection of microscopic DNA spots, commonly representing single genes, arrayed on a solid surface by covalent attachment to chemically suitable matrices. DNA arrays are different from other types of microarray, only in that they either measure DNA or use DNA as part of its detection system Researchers have already discovered over 800 different mutations in BRCA1 alone.The DNA microarray is a tool used to determine whether the DNA from a particular individual contains a mutation in genes like BRCA1 and BRCA2. The chip consists of a small glass plate encased in plastic. Some companies manufacture microarrays using methods similar to those used to make computer microchips DNA Microarray is one such technology which enables the researchers to investigate and address issues which were once thought to be non traceable. One can analyze the expression of many genes in a single reaction quickly and in an efficient manner. DNA Microarray technology has empowered the scientific community to understand the fundamental aspects underlining the growth and development of life as well as to explore the genetic causes of anomalies occurring in the functioning of the human body

DNA MICROARRAY TECHNOLOGY Usefulness of the DNA microarray technology; • Can follow the activity of MANY genes at the same time. • Can get a lot of results fast • Can COMPARE the activity of many genes in diseased and healthy cells • Can categorize diseases into subgroups Drawback: • Too much data all at once DNA microarray is used to detect gene expression by analyzing cDNAs produced from mRNAs of a cell type at different times. To measure changes in gene expression levels - two samples' gene expression can be compared from different samples, such as from cells of different stages of mitosis. To observe genomic gains and losses 1. DNA Microarray: Basic Principle: Complementary sequences of nucleotides stick to, or hybridize to, one another. For example, a DNA molecule with the sequence -A-T-T- G-C- will hybridize to another with the sequence -TA-A-C-G- to form double-stranded DNA. Types of DNA Microarray: There are two major types of DNA microarrays

A DNA microarray (also commonly known as DNA chip or biochip) is a collection of microscopic DNA spots attached to a solid surface. Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome. Each DNA spot contains picomoles (10 −12 moles) of a specific DNA sequence, known as probes (or reporters or oligos) DNA MICROARRAY 3 4. PRINCIPLE Hybridization between two DNA strands Microarrays use relative quantitation : Intensity of a feature is compared to the intensity of the same feature under a different condition, and the identity of the feature is known by its position. 4 5. 1.

In general, the probes are shorter than the genes. Critical note: Different probes for the same gene have different binding affinities. Since the affinities are unknown, microarrays produce relative measurements of gene expression. After selecting the desired probes for all genes of interest, the The use of microarray or DNA chip techniques for Candida research has started recently but the number of studies using this technology is increasing rapidly, in order to address important remaining questions about pathogenesis, cell biology, antifungal susceptibility, and diagnosis {NOTE: In a Southern, the target DNA is immobilized on a membrane; in a microarray, the probes are fixed to the slide or chip. In a Southern, the probe is labeled; in a microarray, the DNA being studied is labeled.} Additionally, the amount of signal directly depends on the quantity of labeled target DNA
