MicroRNAs play a major role in controlling the activity of genes in the body. However, with age and some chronic medical conditions, the attacking microRNA numbers dwindle, reducing our ability to respond to viruses.

What is MicroRNAs?

  • MicroRNAs are tiny sequences of moleculesthat are vital to our development, growth and survival. Each microRNA can regulate many thousands of genes.
  • There are thought to be 2,300 identified micro RNAs in the human genome, regulating up to one third of human genes.
  • Each raw human microRNA comprises 83 nucleotides, which are the building-block molecules of genetic material.
  • Micro in size but mighty in power, microRNAs can stop genes from using their instructions to make new protein molecules by blocking and binding to the relevant genetic codes.
