Gene expression. Gene expression is the process by which the genetic code-the nucleotide sequence-of a gene is used to direct protein synthesis and produce the structures of the cell.Genes that code for amino acid sequences are known as 'structural genes'.The process of gene expression involves two main stages:Transcription: the production of messenger RNA (mRNA) by the enzyme RNA polymerase, and the processing of the resulting mRNA molecule.enes that code for amino acid sequences are known as 'structural genes'.

In the 1950s the peace sign, as it is known today, was designed as the logo for the British Campaign for Nuclear Disarmament and adopted by anti-war and counterculture activists in the United States and elsewhere. The V hand signal and the peace flag also became international peace symbols.
Map of the 2011 United States Peace Index 2011. States appearing more green are ranked as more peaceful; states appearing more red are ranked as less peaceful. The United States Peace Index (USPI) is a measurement of American States and cities by their peacefulness. Created by the Institute for Economics and Peace, the creators of the Global Peace Index, it is said to be the first in a series of National sub-divisions by their peacefulness.
