transcriptional analysis

Transcriptional analysis is a scientific method used to study how genes are turned on or off in cells by examining the process called transcription. During transcription, a gene's DNA sequence is copied into messenger RNA (mRNA), which then directs protein production. By analyzing the types and amounts of mRNA present in a cell or tissue at a specific time, researchers can understand which genes are active and how they respond to different conditions. This helps reveal how cells function, adapt, and interact, providing insights into health, disease, and biological processes.
