DNA promoters. Computer artwork showing promoter and gene regions along a DNA (deoxyribonucleic acid) molecule. A promoter is a DNA sequence that acts as an on/off switch for the gene,or genes,that it precedes. Genes encode the body's genetic information,determining each cell's structure,function and behaviour. DNA is packaged into chromosomes (x-shaped) in the cell nucleus | |
