Work
Our genome can be likened to an instruction manual for all cells in our body. Every cell contains the same set of instructions. Yet, different cell types have very distinct characteristics. These differences arise from gene regulation, which allows each cell to select only the relevant instructions. In 1993, Victor Ambros and Gary Ruvkun discovered microRNA, a new class of tiny RNA molecules that play a crucial role in gene regulation. This new dimension to gene regulation is fundamentally important for how organisms develop and function.
