Regulated Switching
what is the selective advantage to have a genetic mechanism to adjust or switch genes on and off?
ap bio question help please!
If you are considering eukaryotes it should be noted that, in general terms, the lack of a gene is "off" (the opposite is true for bacteria and Archaea) and, therefore, gene expression must be switched on (or off in the second case). E 'of vital importance that the genes are switched on only when necessary and, consequently, gene regulation is to ensure some genes are switched on only when necessary for example, genes are switched on and off during the different stages of development. The control of expression gene ensures the conservation of energy and agencies to maintain the proper functioning of such would not uselful if the genes controlling female menapause have been turned into a baby. This is a very general description of a highly complex area of biology. If you need further explanation or a little more detail is Please write me.
