Transcriptomics is a type of technology that helps us understand how genes in living things affect the way they look and act. Transcriptomics studies the molecules called transcripts, which are made when a gene makes a copy of itself and passes that copy to other cells in the body. Transcripts are like messages that help to control how the cells work and how the body behaves. By studying these transcripts, scientists can learn what kinds of things the biological organism is capable of doing, and how they might be altered to better serve our needs.
