The research area of expression involves studying how genes are activated or turned on to produce proteins that carry out various functions in cells. This includes the regulation of gene expression, mechanisms of transcription and translation, and how external stimuli or environmental factors can impact gene expression. Researchers in this field use a variety of techniques such as gene editing, RNA sequencing, and bioinformatics to study the complex processes involved in gene expression. Understanding gene expression is crucial for advancing our knowledge of biological processes and can have important implications for areas such as medicine, agriculture, and biotechnology.
