DNA-Chips data processing and analysis

Abstract

Modern genetic together with bioinformatics seeks to understand the function of genes, including more than 40,000 genes in the human genome. Recently devel oped for genome analysis, DNA microarrays, also known as gene arra ys or gene chips, are capable of determining the gene expression levels of thousands of genes simultaneously. Gene expression (oft en simply expression) is the process by which a gene's information is converted into the structures and functions of a cell. In other words, it is a process by which gene's information is converted into the proteins by cells. So a gene gets to express itself. In combination with classification methods, this technology can be useful in supporting clinical management decisions for patient s. Experimental conditions may include types of cancers, diseased organisms, or normal tissues
