Answer:
regulating gene expression
Explanation:
A non-coding RNA is one that cannot participate in the protein formation process, because it does not code for any of them. Although it appears to have no function, non-coding RNA plays an important role in regulating gene expression, which is how the cell controls the expression of genes, preventing them from being expressed when they are not needed. In this way the cell saves energy and inhibits the accumulation of unnecessary molecules.
