Microarray analysis can be performed to assess differences in gene expression between two different samples. After isolating nucleic acids from the two samples, one sample is labeled with a dye that ...

In each type of cell, like a muscle cell or a skin cell, different genes are expressed (turned on) or silenced (turned off). If the cells that are turned on mutate, they could—depending on what role ...

Microarrays are used to detect the expression of a diverse range of thousands of genes. They include microscopic slides that can be printed with a spot of a known sequence of DNA. This sequence then ...
