WebGene expression is a tightly regulated process that allows a cell to respond to its changing environment. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made. There are two key steps involved in making a protein, transcription and translation. WebInformation from a gene is used to build a functional product in a process called gene expression. A gene that encodes a polypeptide is expressed in two steps. In this process, information flows from DNA \rightarrow → RNA \rightarrow → protein, a directional relationship … WebDec 24, 2024 · To monitor expression profiles along each developmental stage in C. elegans, a real-time monitoring luminometer system was used, and our method detected the expression profile in a single animal.
