WebOverview: Gene expression and the genetic code Genes that provide instructions for proteins are expressed in a two-step process. In transcription, the DNA sequence of a gene is "rewritten" using RNA nucleotides. In eukaryotes, the RNA must go through additional processing steps to become a messenger RNA, or mRNA. WebGene regulation is the process of controlling which genes in a cell's DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular organism may express very different sets of genes, even though they contain the same …

WebWhether or not there are multiple start and stop codons depends on what you mean by "start codon" and "stop codon". The start codon has the sequence "AUG", and the stop codon has the sequence "UAG", "UAA", or "UGA". Both the pre-mRNA and the mature-mRNA can, and usually do, contain multiple instances of all of these sequences.

WebMany signaling pathways cause a cellular response that involves a change in gene expression. Gene expression is the process in which information from a gene is used by the cell to produce a functional product, typically a protein. It involves two major steps, transcription and translation.

WebA repressor is a type of protein that inactivates the expression of the lac operon genes by binding to the DNA of the lac operon. The lac operon in E. coli controls the gene expression of the enzymes that digest lactose in the cell. In the absence of lactose, the lac operon will turn off and gene expression will be inactivated.
