WebGene regulation and expression. The activity of a cell depends on its ability to use the information in the genes to make specific amounts of specific proteins at specific times and places. Developmental genetics examines how patterns of gene expression and regulation control the development of a multicellular organism from a single cell. Any step of gene expression may be modulated, from signaling to transcription to post-translational modification of a protein. The following is a list of stages where gene expression is regulated, where the most extensively utilized point is transcription initiation, the first stage in transcription: • Signal transduction • Chromatin, chromatin remodeling, chromatin domains

WebTranscription is the first step of gene expression. During this process, the DNA sequence of a gene is copied into RNA.
