microarray data

Microarray data involves measuring the activity of thousands of genes at once to understand how they behave in different conditions. Using tiny chips with many DNA spots, scientists can see which genes are turned on or off in a sample, such as cancerous tissue versus normal tissue. This helps identify patterns and potential targets for diagnosis, treatment, or research. Essentially, microarrays provide a snapshot of gene expression levels across the genome, revealing how cells respond to various stimuli or states.
