Summary[edit]
| Description |
English: (Taken from Cancer.gov)
At any given time in each cell in the body, thousands of different genes are active. Until recently, it has not been possible to capture and compare the patterns of gene expression present in different cells in any systematic way. DNA microarrays allow the comparison of thousands of genes that can be measured simultaneously, and the information gained using these arrays is dramatically changing cancer-treatment decisions. A DNA microarray is a thin-sized chip that has been spotted at fixed locations with thousands of single-stranded DNA fragments corresponding to various genes of interest. A single microarray may contain 10,000 or more spots, each containing pieces of DNA from a different gene. A single gene chip can even hold representative fragments from the entire human genome. |
