Genome regulation consists of many mechanisms that are utilized in the cell. These mechanisms can either increase or decrease the production of specific gene products: RNA and proteins. Gene regulation is used in biology to describe metabolic pathways that respond to the environment. Any step in gene expression (transcription, translation, RNA processing, and modification of a protein) can be seen as gene regulation.

Gene expression plays an essential role in viruses, prokaryotic and eukaryotic cells because it increases the ability of an organism to adapt to its surroundings and allows the cell to express a particular protein when it is needed. Furthermore, in multicellular organisms gene expression comes from the process of cellular differentiation and morphogenesis, which leads to different types of cells being created to synthesis different proteins.

Any step in gene expression can be modulated to increase or decrease the reaction activity. The following list are the stages where gene expression can be regulated

  • Transcription
  • Chromatin domains
  • Post-transcriptional modification
  • RNA Transport
  • Translation
  • mRNA degradation

The recommended targets are real, but the largest health gain is between doing nothing and doing a little. That is the part worth knowing if you are starting from nothing.

Sleep is not one state but a cycle through several, each doing different work. Most sleep disorders are a failure to complete that cycle rather than a shortage of hours.
