Gene Expression
Gene expression is the process by which the genetic information encoded in DNA is used to produce proteins and other molecules that are essential for the functioning of living organisms. It is one of the key steps by which cells read the instructions stored in the DNA and use them to build the proteins and other molecules that allow normal functioning of the organism. By understanding gene expression, scientists are able to decipher how a gene functions, and how mutations in the gene can lead to disease or other changes in the organism. Additionally, gene expression is the basis for understanding how mutations and genetic variations may influence an organism's phenotype, or physical characteristics. An understanding of gene expression can thus help scientists to design better treatments for genetic diseases and to improve the efficiency of crop plants used for food production.
