Precise control of gene expression—ensuring that cells make the correct components in the right amount and at the right time—is vital for all organisms to function properly. Cells must regulate how genes encoded in the sequence of DNA are made into RNA molecules that can carry out cellular functions on their own or be further processed into proteins.
