For most, Christmas is a time of goodwill, sharing, and joy. This was not the case for the small town of Chehalis, Washington on Christmas Eve, 1985. Six days earlier, Edward Maurin and his wife Minnie had been reported missing. They were 83 and 81 years old, respectively.
Gene expression is the process by which the information encoded in a gene is used to direct the assembly of a protein molecule. The cell reads the sequence of the gene in groups of three bases. Each group of three bases (codon) corresponds to one of 20 different amino acids used to build the protein.ene expression is the process by which the information encoded in a gene is used to direct the assembly of a protein molecule.

Diagram showing at which stages in the DNA-mRNA-protein pathway expression can be controlled. Gene expression is the process by which the heritable information in a gene, the sequence of DNA base pairs, is made into a functional gene product, such as protein or RNA. The basic idea is that DNA is transcribed into RNA, which is then translated into proteins. Proteins make many of the structures and all the enzymes in a cell or organism. Several steps in the gene expression process may be modulated (tuned).
