 Serial analysis of gene expression

Serial Analysis of Gene Expression (SAGE) is a technique used to measure the expression levels of genes in a given sample. It provides a quantitative assessment of gene expression by capturing short sequences of DNA tags that correspond to different genes. Here’s a brief overview of how SAGE works and its significance: ### Overview of the SAGE Process: 1. **Sample Preparation**: Total RNA is isolated from a biological sample, such as tissue or cells.
