RNA (ribonucleic acid) is a crucial molecule that plays a central role in the translation of genetic information from DNA into proteins. There are three main types of RNA: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Each type of RNA has a unique function:

  • Precision medicine: RNA-based therapies offer promising opportunities for treating genetic disorders and cancers.
  • Off-target effects: unintended consequences of RNA-based therapies can lead to further complications or even exacerbate existing conditions.

      • The US is home to some of the world's leading institutions in genetics, molecular biology, and medicine, making it an ideal hub for RNA research. The National Institutes of Health (NIH), the National Science Foundation (NSF), and the US Department of Agriculture (USDA) are just a few examples of organizations that have invested heavily in RNA-related research. This significant investment has led to a better understanding of RNA's role in various diseases and has paved the way for innovative treatments and therapies.
