Gene regulation allows for increasing organism complexity. It’s also efficient: only those genes required by the cell are expressed. Gene regulation controls how much of a protein is produced and how often it’s produced, reducing waste and conserving energy. 5’ 5’ large subunit ribosome ...

The translation of mRNA can also be controlled by a number of mechanisms, mostly at the level of initiation. Recruitment of the small ribosomal subunit can indeed be modulated by mRNA secondary structure, antisense RNA binding, or protein binding.
