Now, a study from researchers at Rockefeller University and Columbia University has identified a protein that recognizes a chemical instruction tag affixed to an RNA sequence, an important step in the decision-making process. The team state that their findings help to explain how the destiny of an RNA sequence is achieved. The opensource study is published in the journal Cell.
Some RNA sequences have the ability to form a double helix, much like DNA. Scientists have recently successfully crystallized a short RNA sequence and used data to confirm the hypothesis of a poly (rA) double-helix.
