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.

In a multicellular organism, usually every cell contains the complete genome. All genes are present in every nucleus. However, in any given cell, only some of the genes are actually producing mRNA. Many of the genes are inactive and never do anything. Other genes only produce mRNA at certain points in the life of a cell or in response to certain conditions. The production of mRNA is known as gene expression. Genes that do not produce mRNA and do not contribute to the phenotype are not being expressed.
