Answer:
Promoter Strength
Explanation:
More than increasing mRNA stability, the promoter strength can be tuned to increase the gene expression by producing more quantities of the mRNA. The strength is based on efficient promoter recognition and rapid binding of the DNA polymerase.
hope it helps : )
